Regrowing Limbs?

3/21/08. Many years ago I witnessed the following as a counselor at a camp. An 8 year old one-armed boy was getting a drink at a drinking fountain. When he finished, the boy behind him asked him if his arm would grow back. The one-armed boy said, "I was born this way. I don't think it grows back."

This Scientific American article on regenerating limbs addresses this question.
