For decades, muscle aging was attributed mainly to intrinsic defects within myofibers or to the exhaustion of muscle stem cells, known as MuSCs. The review, drawing on recent single-cell RNA sequencing, spatial transcriptomics, multimodal atlases, and lineage-tracing studies, contends that these explanations are incomplete. Instead, aging reshapes the entire cellular ecosystem: stem cells lose regenerative competence, fibro-adipogenic progenitors become locked into pro-fibrotic states, immune populations fail to resolve inflammation, vascular support declines, and neuromuscular junctions undergo incomplete reinnervation. No single defect explains the decline; rather, it is the desynchronization of the whole system that drives tissue deterioration.

The fate of muscle stem cells illustrates this population-level remodeling. In geriatric mice aged twenty months or older, a fraction of MuSCs loses the capacity for reversible quiescence and drifts into a pre-senescent state, impairing later activation, proliferation, and self-renewal. Time-resolved trajectory analyses show that aged stem cells broadly preserve the overall sequence of activation and differentiation, but their responses are delayed and progress with highly heterogeneous kinetics. Epigenetic instability contributes to this decline: age-associated depletion of S-adenosylmethionine, a critical methyl donor, weakens repressive histone methylation and heterochromatin architecture, promoting DNA damage and apoptosis. Restoring intracellular SAM levels in experiments re-established heterochromatin domains and mitigated age-related regenerative defects.

One of the most provocative concepts in the review is what the authors call cellular survivorship bias. In aged stem cells, elevated expression of the tumor suppressor NDRG1 strongly suppresses mTOR signaling, a principal pathway governing cellular activation and expansion. This appears to function as a cellular brake that prioritizes long-term survival under chronic inflammatory and oxidative stress at the expense of rapid tissue repair. Pharmacologically inhibiting NDRG1 temporarily restores youthful activation and accelerates early repair, but repeated injury cycles lead to severe cellular stress and depletion of the remaining stem cell pool. The surviving cells in aged muscle, in other words, are not optimized for regeneration but selected for persistence under hostile conditions.

Immune dynamics add a second layer of dysfunction. After injury, platelets release chemokines such as CXCL4 and CXCL5 that recruit neutrophils and monocytes, which are later superseded by macrophages clearing debris and supporting myogenesis. In aged muscle, this choreography falters. Inflammatory and senescence-related immune programs persist beyond the window of productive repair, and specific aged M2-like macrophage subsets sustain secretion of pro-fibrotic factors including TGF-beta and osteopontin, driving neighboring stromal cells to deposit excess collagen. Meanwhile, the local accumulation of regulatory T cells, which normally dampen inflammation and supply pro-resolving signals such as IL-10, is markedly reduced or delayed. The result is a temporal mismatch: stem cells need an anti-inflammatory environment to build new fibers, yet the aged niche remains saturated with early inflammatory signals.

Fibro-adipogenic progenitors, or FAPs, are central players in this degenerative relay. In young tissue they transiently expand after injury, secrete extracellular matrix components that support myogenic progenitors, and then either self-eliminate or return to quiescence. Aging destroys this plasticity. Single-cell and spatial analyses reveal that aged FAPs diverge into aberrant states marked by osteopontin, Sca1, Dpp4, or, in human atlases, CD90 expression, all associated with chronic inflammation and fibrosis. Crucially, not all FAPs fail; subpopulations with anti-inflammatory, pro-regenerative signatures persist. The pathology is therefore not wholesale corruption of the stromal compartment but a loss of temporal plasticity, the inability to exit fibrotic states once repair is complete, leading to fibro-adipose remodeling that progressively replaces muscle with scar and fat.

The communication breakdown between stem cells and stromal cells is particularly well documented. FAP-derived WISP1 activates AKT signaling in MuSCs to promote productive proliferation, while fibronectin in the niche regulates adhesion and polarity through integrin-FAK signaling. Both supports decline with age. At the same time, epigenetically perturbed aged stem cells secrete IL-6, osteopontin, and CCN2, factors that push adjacent FAPs toward excessive expansion and collagen production. Senescent stem cells thus act not as passive casualties but as active instigators, propagating their defects through paracrine signaling. Genetic knockdown of CCN2 in aged MuSCs improves regenerative outcomes and attenuates fibrosis, while forced overexpression compromises engraftment and stimulates fibroblast expansion.

Senescence amplifies the damage through additional channels. Senescent FAPs secrete CCL2 and osteopontin, which entrap macrophages in a pro-inflammatory state and sustain a self-reinforcing macrophage-FAP feedback loop. In progeroid and dystrophic mouse models, eliminating senescent cells with the senolytic compound fisetin restores the stem cell pool and regenerative efficacy. Stress-induced senescent myoblasts release extracellular vesicles carrying senescence-associated cargo that induces secondary senescence in endothelial cells, compromising the vasculature repair depends on. Another senescent-cell product, the lipid 15d-PGJ2, covalently modifies the HRas protein in healthy neighboring myoblasts, hyperactivating ERK signaling and blocking myogenic differentiation. These findings show that the senescence-associated secretory phenotype extends well beyond soluble cytokines to transferable, non-protein signals.

The neuromuscular junction constitutes a specialized microdomain where these failures converge. Synaptic destabilization and motor unit remodeling often precede measurable sarcopenia, producing a mosaic of denervated, reinnervated, and unstable myofibers. Terminal Schwann cells guide regenerating axons back to motor endplates, and their ablation in adult mice severely impairs reinnervation and force recovery. Mesenchymal progenitors near motor axons supply trophic support, most notably the protein BMP3B, whose expression declines with age in both mice and humans; sustained expression in aged mice attenuates neuromuscular degeneration, muscle atrophy, and functional decline. Intriguingly, osteopontin displays context-dependent duality: it drives chronic fibrosis in the broader stroma yet acts as an indispensable neurotrophic factor at the synapse, a caution against blunt therapeutic targeting.

The review closes with a sober assessment of what remains unknown. Most ligand-receptor interactions proposed by computational analyses of omic data are still correlative, and only a limited set of signaling pathways, including WISP1 supplementation, CD47 blockade, and senescent FAP clearance, have been functionally validated in vivo. A further challenge is the translational gap between acute, synchronized murine injury models and the chronic, insidious muscle attrition characteristic of human sarcopenia. The authors argue that effective rejuvenation strategies must abandon single-cell targets in favor of restoring the entire multicellular network: stem-stromal crosstalk, immune resolution, vascular support, and neuromuscular communication. Treating aging muscle as an interconnected system, they conclude, offers the most realistic path toward dismantling degenerative loops and preserving strength in old age.

GlycoRNAs first burst onto the molecular biology scene in 2021, when researchers reported that small RNAs can be decorated with N-glycans and displayed on the surfaces of living cells. That discovery overturned the long-standing assumption that glycosylation, the attachment of sugar chains, was an exclusive feature of proteins and lipids processed through the secretory pathway. Subsequent work has linked surface glycoRNAs to processes such as neutrophil recruitment, and imaging methods such as ARPLA have allowed researchers to visualize them in single cells. Yet the functions of glycoRNAs, particularly those exported from cells on EVs, have remained largely unexplored. The new study addresses this gap by systematically profiling the glycoRNA content of different vesicle subtypes and asking whether those molecules matter for vesicle function.

Central to the research is a chemical biology strategy based on metabolic labeling. The team used bioorthogonal handles, chemical tags that can be introduced into glycans inside living cells without perturbing native biochemistry, to mark glycoRNAs as they are synthesized. Because these azide-bearing tags react selectively with complementary probes, the researchers could selectively enrich, detect, and sequence glycoRNAs associated with EVs, separating them from the sea of unmodified RNAs that dominate vesicle cargo. This approach, combined with an EV-focused proximity assay the authors call EV-CAP, allowed sensitive detection of glycoRNAs on individual vesicles and produced the most expansive catalog to date of the extracellular vesicle glycoRNA landscape.

With that toolkit in hand, the researchers examined how glycoRNA profiles differ across vesicle types, cell types, and even culture conditions. They found that large EVs carry glycoRNA repertoires that vary with the producing cell type and with the passage number of the cells, meaning the vesicle glycoRNA fingerprint shifts as cells age in culture. In experiments with colon cancer cell lines, specific glycoRNA species such as those derived from small nucleolar RNAs, including SNORD1B and U2, could be detected on large EVs, and machine-learning-style dimensionality reduction by t-distributed stochastic neighbor embedding separated cell lines based purely on their vesicle glycoRNA fluorescence signatures. Notably, a single lEV glycoRNA species achieved strong discrimination between non-tumor colon cells and colon cancer cells, suggesting diagnostic potential.

The study also documented dynamic changes in vesicle glycoRNA content over time. In SW620 colon cancer cells grown through successive passages, the signals of U8 and U2 glycoRNAs on large EVs decreased as passage number increased, whereas SNORA21 glycoRNA signal rose. This passage-dependence indicates that glycoRNA trafficking onto vesicles tracks the physiological state of the producing cell, supporting the idea that EV glycoRNAs could serve as biomarkers of cell state. Small EVs, meanwhile, displayed glycoRNA profiles distinct from those of their large vesicle counterparts, pointing to vesicle-specific sorting mechanisms that determine which glycoRNAs are loaded into which parcels.

Functionally, the researchers demonstrated that EVs deliver their glycoRNAs into recipient cells, and that glycoRNAs subsequently appear in EVs secreted by those recipient cells. Using a clever double-labeling scheme, the team distinguished where these second-generation glycoRNAs came from. Donor EV glycans carried azide tags detectable with one fluorescent probe, while newly synthesized RNAs in the recipient cells were labeled with 4-thiouridine and visualized with a second chemistry. Förster resonance energy transfer signals, which report when two fluorophores sit within nanometers of each other, revealed that some recipient-cell EV glycoRNA signals arise from glycoRNAs made fresh by the recipient cell, while others trace back to material inherited from the donor vesicles. GlycoRNA transport, in other words, is bidirectional and involves both new synthesis and cargo recycling.

Perhaps the most striking finding concerns regulation of EV uptake itself. When the researchers pre-hybridized EV-associated glycoRNAs with sequence-specific complementary DNA probes targeting species such as SNORA67, SNORD104, or SNORA21, uptake of the vesicles by recipient cells dropped dramatically. Control experiments with non-complementary DNA, or with vesicles from cells in which the corresponding small nucleolar RNAs had been knocked down, reinforced the specificity and importance of the effect. The blockade was observed in both MDA-MB-231 breast cancer cells and MCF-7 cells, and the team showed that the hybridization strategy altered vesicle surface properties as measured by zeta potential. Importantly, an endocytosis inhibitor, genistein, also reduced EV-mediated glycoRNA transport, linking the process to vesicle internalization pathways.

These results reframe glycoRNAs as actionable control points in vesicle biology. Because blocking specific glycoRNA species can heavily reduce EV uptake, the molecules behave as determinants of vesicle tropism, the propensity of vesicles to enter particular cell types. That opens the door to engineering vesicles with altered glycoRNA compositions to improve targeted drug delivery, or conversely, to intercepting pathological vesicle communication, for example in cancer, where EVs are known to promote metastasis and immune evasion. The parallels with glycan biology are notable: just as vesicle surface glycans have been exploited as cancer biomarkers, vesicle glycoRNAs may encode information about the producing cell that both recipients and diagnosticians can read.

The study also comes with important technical caveats and resources for the community. Sequencing data have been deposited in the Gene Expression Omnibus under accession GSE297960, and molecular dynamics simulation data are available through Zenodo, giving other labs the raw material to interrogate the glycoRNA landscape independently. Detection assays relied on careful controls, including western blot characterization of vesicle preparations and quantitative comparisons across biological replicates, and the authors note that glycoRNA functions on cell surfaces remain largely unexplored beyond these initial observations. As the field moves forward, questions about how glycoRNAs are synthesized, sorted onto vesicles, and recognized by recipient cells will demand attention. For now, the message is clear: the sugar-coated RNAs riding on extracellular vesicles are both messengers and gatekeepers, and learning their language may prove essential for decoding, and eventually directing, the conversation between cells.

The review, led by Francesca Cristiana Piritore and Maria Teresa Valenti of the University of Verona together with colleagues in Portugal, synthesizes a rapidly expanding body of evidence showing that plant cells actively secrete extracellular vesicles enriched in defense proteins, structural lipids, and regulatory RNAs. These vesicles, typically ranging from 30 to 300 nanometers in diameter, are now recognized as genuine mediators of intercellular communication rather than byproducts of cell wall remodeling. Crucially, vesicle release has been documented not only in intact plant tissues but also in callus and suspension cell cultures maintained in the laboratory, demonstrating that vesicle secretion is an intrinsic cellular process rather than one dependent on organized tissue architecture.

The functional repertoire of plant extracellular vesicles is striking. Early landmark work showed that sunflower vesicles, loaded with defense proteins and cell-wall-modifying enzymes, can bind to and kill cells of the fungal pathogen Sclerotinia sclerotiorum, causing morphological defects, growth retardation, and death in treated spores. More recent studies in Arabidopsis revealed that vesicles released during systemic acquired resistance are packed with immune signaling components and pattern-recognition molecules; recipient plant cells take up these vesicles and mount stronger defenses, reducing the virulence of bacterial and fungal pathogens in both infection assays and neutralization tests. Perhaps most remarkably, plant vesicles carry small interfering RNAs and microRNAs capable of silencing genes in interacting pathogens—direct evidence of cross-kingdom gene regulation mediated by vesicle traffic.

The molecular machinery behind this RNA trafficking is beginning to come into focus. Researchers identified several RNA-binding proteins in Arabidopsis that are secreted via exosome-like vesicles, including argonaute 1, RNA helicases RH11 and RH37, and the annexins ANN1 and ANN2. The helicases selectively associate with vesicle-enriched small RNAs, while the annexins bind them non-specifically; mutants lacking these proteins show reduced small RNA secretion, indicating that they are essential for loading or stabilizing RNA cargo within vesicles. This selectivity suggests a highly evolved mechanism by which plants can directly interfere with gene expression in their antagonists—a capability with obvious biotechnological appeal, though the authors caution that the relationship between cargo selection and specific vesicle biogenesis pathways remains poorly defined.

This is precisely where in vitro plant cell cultures enter the picture. The review highlights that callus and suspension cultures offer something whole plants cannot: a controlled, homogeneous, and potentially scalable environment for studying how vesicles are made, what they carry, and how their cargo can be modulated. Work on Arabidopsis cell cultures showed that vesicle biogenesis depends on the ESCRT trafficking pathway and on the physiological state of the cells, while studies of tobacco demonstrated that vesicles can be reproducibly generated and purified from calli and suspension cultures with morphological features comparable to those derived from whole tissues—although their composition differs, reflecting distinct cellular origins.

The practical advantages of culture-based production are considerable. Plant cell cultures can be maintained in simple, animal-component-free media without serum, reducing upstream costs, ethical concerns, and the risk of contamination by mammalian pathogens. They provide renewable biomass and are compatible with contained bioreactor production, including gentler airlift and temporary immersion systems that permit non-destructive collection of vesicles from the surrounding medium. Because vesicles can be harvested directly from conditioned culture media rather than from disrupted tissue, cultures also reduce interference from intracellular contents released during homogenization—a distinction the authors argue is critical for reproducibility. They draw a sharp line between bona fide extracellular vesicles secreted by living cells and the heterogeneous nanovesicle preparations generated by grinding or blending plant material, which contain membrane fragments, organelle-derived particles, and soluble contaminants that can confound both characterization and functional studies.

Isolation and purification remain the field’s most stubborn obstacles. Plant extracts are rich in pigments, phenolics, starch, polysaccharides, and secondary metabolites that coprecipitate with vesicles and interfere with downstream analysis. Differential ultracentrifugation remains the workhorse method, but high centrifugation forces co-sediment protein aggregates, prompting many laboratories to combine it with size-exclusion chromatography or density-gradient ultracentrifugation, which exploits the characteristic buoyant density of plant vesicles. Polymer-based precipitation offers a low-cost, scalable alternative at the price of contaminant carryover, while newer technologies—tangential flow filtration for pharmaceutical-grade scalability, the EXODUS system using oscillating membrane vibration, hydrophobic interaction chromatography on polymer fiber phases, and label-free microfluidic and acoustofluidic platforms—promise higher purity and throughput, though most still require validation on plant-derived material.

Characterization suffers from an equally fundamental gap: the absence of universal plant vesicle markers. Mammalian extracellular vesicle research relies on well-established markers such as CD9, CD63, and CD81, but no plant equivalents have been validated. Candidate proteins including TETRASPANIN8, PEN3, HSP70, HSP90, and PATL1 are frequently detected, yet their abundance varies with species, tissue, physiological state, and vesicle subpopulation, and antibodies raised against mammalian markers cannot be assumed to recognize plant homologs specifically. The review calls for plant-specific characterization guidelines combining multiple positive markers with negative markers for intracellular contaminants, aligned with the International Society for Extracellular Vesicles’ MISEV framework, alongside standardized reporting of cell-line origin, culture age, subculture number, and growth-regulator regime to guard against somaclonal variation during prolonged propagation.

On the translational side, the momentum is unmistakable. Plant-derived vesicles have shown antioxidant and anti-inflammatory activity, immune modulation, inhibition of tumor cell growth, and promotion of tissue repair in mammalian experimental systems. Cannabis-derived vesicles enriched in cannabidiol reduced the viability of hepatocellular carcinoma cell lines, with activity tracking CBD content across chemotypes. Strawberry and citrus vesicles carrying vitamin C and microRNAs protected human mesenchymal stromal cells from oxidative stress, with encapsulation enhancing the stability and bioavailability of the antioxidant cargo. Engineering strategies are advancing rapidly: LED irradiation exploits the intrinsic photosensitizing properties of vesicles to transiently increase membrane permeability, achieving roughly 80 percent loading efficiency under optimized conditions; electroporation loaded RNA into high-yield vesicles from poplar callus cultures, which were then internalized by Botrytis cinerea hyphae; and genetically modified tobacco plants produced vesicles selectively enriched with artificial microRNAs that induced sequence-specific gene silencing in recipient cells—the first proof of concept that plant vesicles can be programmed for targeted RNA delivery.

The authors are careful to temper enthusiasm with rigor. Most biomedical evidence comes from in vitro systems or acute animal models, with little known about biodistribution, pharmacokinetics, immune interactions, and long-term safety following systemic administration. Functional studies must exclude contributions from co-isolated free metabolites, and dose-response relationships, uptake mechanisms, and off-target effects remain largely unexplored. Yet the convergence of plant cell biology, vesicle research, and biotechnology that this review charts suggests a coherent path forward: controlled cultures as model systems for understanding vesicle-mediated communication, and as production platforms for biologically defined vesicles whose cargo, purity, and function can finally be specified, standardized, and translated.

Using fluorescent labeling and advanced imaging, the team tracked how communication travels through these unicellular organisms. They confirmed that chemical signals can diffuse between cells and that membrane-bound vesicles also participate in cargo movement. But beyond these pathways, the study highlights an additional route: cytoplasmic material can be transferred through nanotubes that physically link distant cells.

Tunneling nanotubes (TNTs) proved capable of carrying cellular components and organelles across separation distances reaching about 100 micrometers. This is a crucial scale because it allows exchange beyond what diffusion alone would readily accomplish within relevant timeframes.

The nanotubes were not merely structural artifacts. The researchers tested whether TNTs persist under cytoskeletal stress by disrupting actin polymerization with depolymerizing agents. Remarkably, the protrusions continued to function, indicating that TNT-mediated transfer can remain operational even when the actin network is perturbed.

Their microscopy revealed multiple TNT architectures, including branching structures capable of connecting more than two cells at once. Such branching offers a plausible mechanism for routing material across a network rather than relying on simple pairwise contact.

The work also reports occasional cross-species connectivity, with nanotubes observed bridging cells from different amoeba species. This raises questions about what molecular features enable compatibility between cell types and how such bridges may influence ecological interactions.

Intercellular material transfer is a defining feature of multicellular life, where coordinated behavior depends on regulated exchange of signals and internal components. The authors propose that tunneling nanotubes could represent an evolutionary bridge from solitary unicellular signaling toward more integrated multicellularity.

Overall, the study reframes communication in early-branching eukaryotes by adding a direct, physical form of connectivity to the established chemical and vesicle-based modes. For viral-style science coverage, the headline is clear: social amoebae may be “networked” not only by messages, but by literal cellular bridges.
