Cloning Capsized?
Ted Agres | Aug 19, 2001 | 10+ min read
Biopharmaceutical researchers fear how pending federal legislation outlawing the cloning of human cells will restrict their abilities to find cures for major degenerative diseases.1,2 Some also see lawmakers impinging on established nonhuman cloning techniques essential for the discovery of new drugs and therapies. The source of all this worry? The US House of Representatives passed July 31 by a wide margin a bill (H.R. 2505) sponsored by Reps. David Weldon (R-Fla.) and Bart Stupak (D-Mich.) th

But, just as antibodies are finding increasing utility in cell biology, a new Food and Drug Administration classification for those products with clinical utility may affect researchers' access to the important technology (see accompanying story). Monoclonal History MAbs were born in 1975, when Georges Kohler and Cesar Milstein at the Medical Research Council Laboratories in Cambridge, England, fused two types of cells to form a hy

if (n == null) The Scientist - The Immune Response The Scientist 9[18]:18, Sep. 18, 1995 Tools The Immune Response By Holly Ahern Imagine that you've just cloned a gene for a bacterial enzyme with unique structural properties and you want to find out more about it. What natural role does the enzyme play, you wonder, and do organisms other than bacteria produce it? To answer these questions, you could screen countless genomic libraries for clones bearing si

A Paradigm Shift in Stem Cell Research?
Ricki Lewis | Mar 5, 2000 | 9 min read
Photo: E.D. Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.

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.
