About the Cover


After Prometheus stole fire from the gods, Zeus assigned "a long-winged eagle, which used to eat his immortal liver; but by night the liver grew as much again every day" (from Hesiod's Theogony). Nowadays, the study of tissue regeneration has become an integrating interface where molecular and cellular biology explore mechanisms related to whole organ growth. See the special section beginning on page 59 and the editorial on page 15. [Source: Linda A. Shab and George K. Michalopoulos. Illustration: Elizabeth Carroll]
