Synthetic Circuits Reveal the Key to Rewinding the Cellular Clock
Charlene Lancaster, PhD | Mar 12, 2024 | 4 min read
Using a circuit-based system, scientists determined the ideal transcription factor levels to promote the successful reprogramming of fibroblasts into induced pluripotent stem cells.

Stem cells for brain cancer

FEATUREThe Ecology of Tumors Stem cells for brain cancer BY PETER B. DIRKSNeural stem cell biology took off in 1992 when Brent Reynolds and Samuel Weiss, working at the University of Calgary, discovered that culturing mammalian brain cells in serum-free conditions (in EGF and bFGF), yielded clonally derived colonies of undifferentiated neural cells (neurospheres). This culture system demonstrated that cells within these colonies showed cardinal pr

Photomicrographs of NOD/SCID mouse liver sections from mice transplanted with purified human Lin-CD38-CD34-C1qRp+ cells isolated from umbilical cord blood, harvested 8-10 weeks post-transplant. Tissue sections were stained for HSA (hepatocyte-specific antigen) or c-met
Americas Stem Cell Mess

By Josephine Johnston America’s Stem Cell Mess Other countries have laws that provide researchers with legal and moral clarity. Modified From © Klaus Guldbrandsen / Photo Researchers, Inc. It’s hard not to feel sorry for American embryonic stem cell (ESC) researchers. Over the dozen years since the cells were first derived, they’ve been expected to meet federal rules that change with each president, research guidelines from the National Acad
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--
