A nanofiber matrix for healing
A matrix made of gelatin nanofibers on a synthetic polymer microfiber mesh may provide a better way to culture large quantities of healthy human stem cells. Developed by a team of researchers led by Ken-ichiro Kamei of Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS), the 'fiber-on-fiber' (FF) matrix improves on currently available stem cell culturing techniques. Researchers have been developing 3D culturing systems to allow human pluripotent stem cells (hPSCs) to grow and interact with their surroundings in all three dimensions, as they would inside the human body, rather than in two dimensions, like they do in a petri dish. Pluripotent stem cells have the ability to differentiate into any type of adult cell and have huge potential for tissue regeneration therapies, treating diseases, and for research purposes. Most currently reported 3D culturing systems have limitations, and result in low quantities and quality of cultured cells. Ka...
