Closing the Regeneration Gap
2 April 1998 7:00 pm
Today is the 70th birthday of Elizabeth Hay, an embryologist at Harvard Medical School who, through pioneering studies on regeneration of amphibian limbs, has shed light on the cellular mechanisms that transform normal cells into tumors. She made some of the first electron micrograph autoradiographs, a technique for producing a photographic record of cells and tissues regenerating after exposure to radiation. Hay has written and edited several textbooks on cytology and developmental biology. (The 4 April 1997 issue of Science--available to Science Online subscribers--includes a series of articles on recent work on regeneration.)
