Stem Cells Battle for Space

Johns Hopkins Medicine — Fri, 04 Dec 2009 16:00:00 EST

The body is a battle zone. Cells constantly compete with one another for space and dominance. Though the manner in which some cells win this competition is well known to be the survival of the fittest, how stem cells duke it out for space and survival is not as clear. A study on fruit flies published in the October 2 issue of Science by Johns Hopkins researchers describes how stem cells win this battle by literally sticking around.

Endocrine Society Calls for Expanded Scope and Funding for Stem Cell Research

Endocrine Society — Tue, 27 Oct 2009 11:00:00 EST

Stem cell research holds great promise for the treatment of millions of Americans with debilitating and possibly fatal diseases. Current legislation and guidelines, however, continue to limit researchers' endeavors in unlocking the potential breakthroughs that stem cell research can provide. To address this concern, today The Endocrine Society issued a Position Statement calling for an increase in NIH funding for stem cell research as well as expanding the scope of funding to include promising yet neglected areas of stem cell research.

Team Grows Retina Cells from Skin-derived Stem Cells

University of Wisconsin-Madison — Mon, 24 Aug 2009 15:00:00 EST

A team of scientists from the University of Wisconsin-Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells -- suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.

New Method Takes Aim at Aggressive Cancer Cells

Whitehead Institute for Biomedical Research — Thu, 13 Aug 2009 12:00:00 EST

A multi-institutional team has discovered a chemical that works in mice to kill the rare, aggressive cells within breast cancers that can seed new tumors. These cells, known as cancer stem cells, are thought to enable cancers to spread "" and to reemerge after seemingly successful treatment.

Technique Enables Efficient Gene Targeting in Human Embryonic Stem Cells

Whitehead Institute for Biomedical Research — Thu, 13 Aug 2009 10:30:00 EST

A novel technique allows researchers to efficiently modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to Whitehead scientists. For years, scientists have easily swapped genes in and out of mouse ESC or iPS cell genomes, but have had a notoriously difficult time disrupting or inserting genes into their human equivalents.
