Using a circuit-based system, scientists determined the ideal transcription factor levels to promote the successful reprogramming of fibroblasts into induced pluripotent stem cells.
Cultivating Policy from Cell Types
Eugene Russo | May 27, 2001 | 7 min read
For better or worse, stem cell science has become inextricably married to stem cell politics. Policymakers who oppose public financing of embryonic stem cells have used recent adult stem cell findings to argue for a dismissal of the NIH stem cell guidelines (see "On the Brink," page 1). The guidelines, finalized last summer during the Clinton administration, call for funding the use, but not derivation, of human embryonic stem cells (ESCs); the pro-life Bush administration appears ready to ban t

Ever since the isolation and culturing of human pluripotent stem cells in 1998, the debate has intensified regarding legal, ethical, and social ramifications associated with research use of these cells that are capable of developing into many different specialized tissues.1, 2 In order for the National Institutes of Health to clarify its position on research with these cells, in January 1999, it placed a moratorium on use of human pluripotent stem cells derived from embryos and fetal tissue in f

Illustration: A. Canamucio Cell biology has become the third overlapping core discipline of modern biology, along with biochemistry and genetics. Progress over the century--since E.B. Wilson's classic book1 elegantly framed many of the questions of cell biology--has relied on advances in technology and yielded fascinating insights into the ways that cells work. We now have an unprecedented understanding of the structure, organization, and functions of cells. As the number of completed ge
