Stem cells proliferate, regenerate

National report -- In a study that could have implications for faster wound healing in the future, Australian researchers have dispelled the belief that only epidermal stem cells are capable of tissue regeneration; short term and long term. They report in the February 2004 issue of The Journal of Clinical Investigation that significant proliferative and tissue-regenerative capacity resides in the more mature progeny of keratinocyte stem cells - including early differentiating cells.
