Abnormal Limb Development in Rana catesbeiana

open access: yesExperimental Biology and Medicine, 1965
SummaryPreliminary evidence has been presented which indicates that in the larval anuran, Rana catesbeiana, stimulation of the anterior limb bud field by cutting leads to the formation of supernumerary limbs. The abnormal appendages were conveniently categorized as duplicate or triplicate structures.
