Moving Beyond Embryonic Stem Cells: Encouragement On the Horizon PDF Print E-mail
Saturday, 09 July 2011 01:45

For nearly two decades, the medical world and the American public have grappled with the lightning-rod topic of stem cells, in particular the controversy surrounding cells from human embryos. But when researchers four years ago successfully "reprogrammed" adult body cells to become stem cells, some thought the ethical debate was nearly over. Those redirected cells, known as induced pluripotent cells, or iPS cells, show potential as therapy.

A Mother's Salt Intake Could Be Key to Prenatal Kidney Development PDF Print E-mail
Saturday, 09 July 2011 01:29
A new animal study from Europe has drawn an association between pregnant mothers' sodium intake and their newborn's kidney development. Among the most significant aspects of the study's findings is that either too much or too little salt during pregnancy had an adverse effect on the prenatal development of the offspring's kidneys.

Scientists Grow Brain Cells from Skin: Cancer Cells and Stem Cells Share Same Origin, Research Shows PDF Print E-mail
Thursday, 21 July 2011 00:39
Oncogenes are generally thought to be genes that, when mutated, change healthy cells into cancerous tumor cells. Scientists at the Keck School of Medicine of the University of Southern California (USC) have proven that those genes also can change normal cells into stem-like cells, paving the way to a safer and more practical approach to treating diseases like multiple sclerosis and cancer with stem cell therapy.

Protein Switch Controls How Stem Cells Turn Into New Heart Tissue PDF Print E-mail
Tuesday, 19 July 2011 00:46
Oxford University researchers have identified a protein that can direct stem cells to become either new heart muscle or blood vessels. The research, which was carried out in zebrafish, offers insight into how it might be possible one day to generate tissues to repair the human heart after damage inflicted by a heart attack.

'Pure' Human Blood Stem-Cell Discovery Opens Door to Expanding Cells for More Clinical Use PDF Print E-mail
Thursday, 14 July 2011 01:51
For the first time since stem cells were discovered 50 years ago, scientists have isolated a human blood stem cell in its purest form -- as a single stem cell capable of regenerating the entire blood system. This breakthrough opens the door to harnessing the power of these life-producing cells to treat cancer and other debilitating diseases more effectively.
