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

Image: ©2001 MacMillan Publishers Ltd.  PLURIPOTENT-CELL PIPELINE: To obtain embryonic germ cells, researchers culture primordial germ cells (PGCs) dissected from the genital ridge. If left in situ, a PGC develops into spermatozoa or ova after its imprints have been erased and reestablished. Embryonic stem cells come from the blastocyst's inner cell mass.
