New research may help to explain why the location of postnatal neural stem cells in the brain determines the type of new neurons that are generated. The research, published by Cell Press in the July 28 issue of the journal Neuron, demonstrates that a signaling pathway which plays a key role in development also actively regulates the fate of neural stem cells in the adult brain.

 A new plastic surface which overcomes the difficulties associated with growing adult stem cells has been developed, according to scientists.
Standard surfaces have proved limited for growing large amounts and retaining the stem cells' useful characteristics.

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.

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.

Stem cells from early embryos can be coaxed into becoming a diverse array of specialized cells to revive and repair different areas of the body. Therapies based on these stem cells have long been contemplated for the treatment of diabetes, but have been held back by medical and ethical drawbacks.

 Scientists at the Salk Institute for Biological Studies have developed an improved technique for generating large numbers of blood cells from a patient's own cells. The new technique will be immediately useful in further stem cell studies, and when perfected, could be used in stem cell therapies for a wide variety of conditions including cancers and immune ailments.
