Researchers working with flies at IRB Barcelona describe that the concentration of some small intracellular organelles determines the branching capacity of tracheal cells. (more…)
Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, known as Muller…
The underlying cause of male infertility is unknown for 30 percent of cases. In a pair of new studies, researchers at University of California San Diego School of Medicine determined that the reproductive homeobox (RHOX) family of…
Knowing when to hold them, and when to fold them, is a critical skill in professional gambling. But it's also pertinent for cells assessing DNA damage. (more…)
By coating tiny gel beads with lung-derived stem cells and then allowing them to self-assemble into the shapes of the air sacs found in human lungs, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell…
A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the Aug..
Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease. In tissues that t..
Human parthenogenetic stem cells, derived from unfertilized oocytes, can be used without destroying potentially viable human embryos to generate unlimited supply of neural stem cells for transplantati..
Intestinal stem cells are among the most rapidly dividing cells in the body, busily creating new cells to replace the ones that are constantly being sloughed off. But unlike stem cells elsewhere in th..
Signaling a potential new approach to treating diabetes, researchers at Washington University School of Medicine in St. Louis and Harvard University have produced insulin-secreting cells from stem cel..
