Vitamin A and its derivatives, the retinoids, cause specific alterations in the proximo-distal
pattern of regenerating axolotl limbs. In some cases complete limbs grow from carpal level
amputations. If retinoids are responsible for changing the positional information of limb cells,
these compounds may represent valuable probes for investigating the molecular basis of
pattern formation.
