Research Summary: Retinoic acid (RA) is the biologically active metabolite of vitamin A. It is a low molecular weight, lipophilic molecule that acts on the nucleus to induce gene transcription.

RA induces the "super-regeneration" of organs that can already regenerate, such as the urodele amphibian limb, by respecifying positional information in the limb. In organs that cannot normally regenerate, such as the adult mammalian lung, RA induces the complete regeneration of alveoli that have been destroyed by various noxious treatments. In...
