Artificially engineering the intestine

New Rochelle, NY, September 17, 2019-Short bowel syndrome is a debilitating condition with few treatment options, and these treatments have limited efficacy. The ability to grow artificial intestine is a coveted goal with the potential to profoundly improve this outlook. Working toward this target, researchers have created an artificial scaffold that mimics the native small intestinal architecture, complete with villi; this scaffold can incorporate intestinal epithelial cells and be successfully implanted in mice while retaining structural integrity. The work is reported in Tissue Engineering, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. Click here to read the article for free through October 17, 2019.
David J. Hackam, Johns Hopkins School of Medicine, Baltimore, MD, and colleagues present their results in an article titled “Development of Intestinal Scaffolds that Mimic Native Mammalian Intestinal Tissue.” The authors used polyglycerol sebacate to fabricate scaffolds and showed that they have mechanical properties similar to native intestine, are stable in control and digestive media, and can be infiltrated with intestinal epithelial cells for functional intestinal recreation attempts. An additional feature of the scaffold material is its amenability to the future integration of drug and growth factor delivery mechanisms.
“Dr. Hackam and his team at Johns Hopkins, Cornell, and Walter Reed, have beautifully mimicked the microarchitecture of native small intestine using a degradable, poly(glycerol sebacate) scaffold, showing that their approach supports functional intestinal epithelial cells for weeks after implantation,” says Tissue Engineering Co-Editor-in-Chief John P. Fisher, PhD, Fischell Family Distinguished Professor & Department Chair, and Director of the NIH Center for Engineering Complex Tissues at the University of Maryland. “The work has tremendous translational potential.”
