Retinoic acid and limb regeneration--a personal view

Abstract

Here I describe the situation which led up to the descriptions of the dramatic effects of retinoids on the regenerating amphibian limb. The original papers from an Indian group were published in relatively obscure journals but thanks to literature searches were made available for reading. Repetition of this work and its publication in widely read journals spawned the new field of research on the role of retinoids in developing and regenerating limbs.
