Researchers at the Wistar Institute in Philadelphia found that mice lacking the p21 gene regain the ability to regenerate lost tissue, more or less like an amphibian.

According to the Wistar researchers, the loss of p21 causes the cells of these mice to behave more like regenerating embryonic stem cells rather than adult mammalian cells. This means they act as if they (are) creating rather than mending the body.

Their findings, published in the Proceedings of the National Academy of Sciences, provide solid evidence to link tissue regeneration to the control of cell division.
