Alejandro Sanchez-Alvarado (Univ Utah) Part 2: Principles of Planarian Regeneration

Planarians have attracted the attention of generations of biologists. It is not hard to see why: cut a worm into two fragments and each fragment regenerates a complete organism. Cut it into 8 fragments and each individual fragment will go on to regenerate a complete animal. In this second part of the lecture, I will briefly review the rich history of planarian research, followed by a summary of the central principles of planarian regeneration that have been derived from this extensive, often fascinating body of experimental work.
