Digit regeneration in mice is stimulated by sequential treatment with FGF2 and BMP2 (opens in new tab)

Epimorphic regeneration in mice is stimulated at a non-regenerative digit amputation by sequential treatment with FGF2 and BMP2 (FGF2→BMP2). FGF2 stimulates digit amputation wound cells to form a blastema and BMP2 induces blastema differentiation to regenerate the amputated distal phalangeal element, albeit imperfectly. The formation of a phalangeal growth plate suggests that the induced regenerate recapitulates embryonic development and cell lineage studies show that wound cells that enter t...
