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.

In work that has not yet been peer-reviewed, researchers present evidence that microbes can and do live inside the venom glands of several dangerous species. It remains unclear whether they’re to blame for infections linked to bites.

Stem Cell Discoveries Stir Debate
Douglas Steinberg | Nov 12, 2000 | 9 min read
Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--
