Regeneration induced in the forelimbs by treatment with vitamin A in the froglets of Rana breviceps.
Young froglets Rana breviceps do not possess the power to regenerate forelimbs after amputation through metacarpals. However, 5 min immersion of limb stumps in an oily solution of 150,000 IU vitamin A palmitate immediately after amputation, and once on each of the 3 subsequent days, induced definite though hypomorphic regeneration in 100% cases.
