Pouring Stem Cell Factors into Wounds Could Heal Skin Ulcers

In large patches of ulcerous skin, surviving cells prioritize inflammation and wound closure. That’s what they’re programmed to do. Cells, however, can be reprogrammed—as laboratory procedures have demonstrated. Now cells can also be reprogrammed in living tissue, wounded tissue, to expedite healing. No balm is necessary, unless stem cell factors may be considered a kind of balm.The new approach to cellular reprogramming was developed by a Salk Institute team of scientists led
