1 gene lost = 1 limb regained? Scientists demonstrate mammalian regeneration through single gene deletion
A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing ...
