Fluorescent microscopy image of an embryo model representing four tissue layers of this developmental stage. Cyan-labeled cells are clustered at the top of an ovoid structure, underneath them are yellow-labeled cells and under them red-labeled cells, and surrounding all three layers are white labeled cells.

STARTING POINT: Johns Hopkins' John Gearhart announced at a July meeting that he and a colleague had cultured human embryonic stem cells. Last July, with repercussions from Scottish sheep clone Dolly yet to die down, came news of potentially even greater importance. At the 13th International Congress of Developmental Biology in Snowbird, Utah, held the week of July 12, John Gearhart, a professor of gynecology and obstetrics at Johns Hopkins University School of Medicine in Baltimore, reported

Courtesy of Nadya Lumelsky and Ron McKay  PANCREATIC CELL PUZZLE: A cell sub-population in differentiated embryonic stem cell cultures produces pancreatic islet hormones, insulin (red) and glucagon (green). Although most cells produce only one type of hormone, the cells shown in yellow produce both. The co-production of the two hormones might signify developmental immaturity. The ethical dimension of embryonic stem cell research looms so large in the public consciousness that the underly
