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--

Should the scientific community abandon the 14-day rule for research on human embryos?
Ida Emilie Steinmark, PhD | Jul 5, 2023 | 2 min read
Research on human embryos is usually limited to the first 14 days of development, but as scientific capabilities improve, some argue that it is time to go further.
Debate Over Stem Cell Origins Continues
Ricki Lewis | May 26, 2002 | 7 min read
In science, things are not always as they seem. So it is for transdifferentiation, the apparent interconvertibility of certain specialized cell types and an underlying theme at a symposium on stem cell biology and applications at the recent annual meeting of the American Association for Cancer Research (AACR) in San Francisco. "For the past three years, people have been saying that hematopoietic [blood-forming] stem cells can become just about any tissue, challenging the paradigm that there are
