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.
