Infertility :: Infertile couples willing to donate unused embryos to stem cell research

In a survey of over a thousand patients who have created and frozen embryos as part of fertility treatment, 60 percent said they would be likely to donate unused embryos for stem cell research, according to a study led by researchers at Duke University Medical Center and Johns Hopkins University. The researchers published their findings online in the June 21, 2007 Science Express, the online component of the journal Science, and the study will be published in the journal?s July 6, 2007 print issue.

Stem Cell :: 5 genetic themes key to keeping stem cells in a primitive, flexible state

For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express.

Embryo :: Donated embryos could result in more than 2000 embryonic stem cell lines

In a survey of more than one thousand infertility patients with frozen embryos, 60 percent of patients report that they are likely to donate their embryos to stem cell research, a level of donation that could result in roughly 2000 to 3000 new embryonic stem cell lines.

Infant :: Promising protein may prevent eye damage in premature babies

A protein long thought to be one of the body?s supporting players has quietly been taking a lead role in healthy eyesight, a discovery that could rapidly lead to treatments for babies born before their eyes are finished growing, University of Florida and Harvard Medical School researchers have found.

Stem Cell :: Surrey & Irvine to investigate use of nanomaterials in stem cell therapies

University of Surrey researchers, Dr Alan Dalton and Dr Richard Sear, have received grants totalling ?100k from the SETsquared Applied Collaborative Research Programme and the EPSRC to support collaborative work with the University of California, Irvine, researching the use of nanomaterials in stem cell growth.

Stem Cell :: University of Pittsburgh researchers culture blood-forming stem cells from human fat tissue

Researchers at the University of Pittsburgh School of Medicine have successfully isolated and cultured human hematopoietic stem cells from fat, or adipose, tissue, suggesting that they have found another important source of cells for reconstituting the bone marrow of patients undergoing intensive radiation therapy for blood cancers.

Stem Cell :: Pre-cancerous blood diseases can be products of their environment

When blood-forming stem cells misbehave, causing pre-cancerous conditions that can sometimes even progress to leukemia, the problem might not always lie with them. Rather, two studies in the June 15 issue of the journal Cell, published by Cell Press, reveal that a bad environment might be to blame.

Parkinson’s Disease :: Neural stem cells may reduce Parkinson’s symptoms

Primates with severe Parkinson’s disease were able to walk, move, and eat better, and had diminished tremors after being injected with human neural stem cells, a research team from Yale, Harvard, the University of Colorado, and the Burnham Institute report today in Proceedings of the National Academy of Sciences.

Stem Cell :: Cancer stem cells can go it alone

At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line — established long ago — turned out to behave a lot like cancer stem cells.

Stem Cell :: A twist of fate – Reprogrammed fibroblasts resemble embryonic stem cells

Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.
