Scientists are now able to regrow frog legs. Will it pave the way for human regeneration?

A team at Tufts University and Harvard University has brought scientists a step closer to the goal of regenerative medicine by using a drug cocktail to regrow a frog’s amputated legs.Only a few animals in the world are able to regrow some limbs: salamanders, lizards and crabs.They do it through blastema cells, when a mass formation of stem cells occurs at the end of a stump almost immediately after the limb is lost, so the regrowth process can begin.Frogs are like humans and mammals, however,…
