Repair of this organ after injury is thus a life saving priority. But how do skin cells know when to proliferate and at what rate? In the March 23, 2009 issue of the Journal of Cell Biology, Asst/P Tan Nguan Soon and colleagues reveal that skin fibroblasts use a protein called PPARβ/δ to make sure overlying epithelial cells don't proliferate too quickly. "Proliferation is important in early stages of wound healing," explains Tan. "But excessive proliferation isn't good: you can end up with hypertrophic scarring." Their results highlight how communications between different cell types are critical to maintain the skin as a barrier against the outside world....Tue, 31 Mar 2009 16:00:00 GMT
