  • How nails regenerate lost fingertips

    ‘Really striking’
    “It’s a fantastic paper,” says James Monaghan, a regeneration biologist at Northeastern University in Boston, Massachusetts. “It’s really striking that the cellular mechanisms and signalling pathways, like Wnt and FGF, all seem to be the same as those in salamanders.”

    It seems likely that these mechanisms will also apply to humans and other mammals, since the pathways are conserved, and previous studies have shown that humans also depend on nails to regenerate amputated digit tips.
