UCLA stem cell researchers move toward treatment for rare genetic nerve disease
Led by Dr. Peiyee Lee and Dr. Richard Gatti, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have used induced pluripotent stem (iPS) cells to advance disease-in-a-dish modeling of a rare genetic disorder, ataxia telangiectasia (A-T). Their discovery shows the positive effects of drugs that may lead to effective new treatments for the neurodegenerative disease. iPS cells are made from patients' skin cells, rather than from embryos, and they can become any type of cells, including brain cells, in the laboratory. The study appears online ahead of print in the jour...

Young blood may help rejuvenate old hearts
Conclusion This study finds that sharing the circulation of young and old mice appears to reverse the age-related thickening of heart muscle cells in the older animal, and it seems this could be due to a certain growth factor in the blood of the young animal. The findings will be of scientific interest, and further our understanding of the processes of heart ageing in animals. However, the findings have very limited direct relevance to humans, and do not suggest a new treatment for heart failure. It is also certainly unknown at this point whether increasing levels of this factor in the blood of people with this type of he...

Chemokine Receptors and Neural Stem Cells
Neural stem cells (NSCs) represent a limited population of progenitor cells in the central nervous system that sustain their self-renewal and multipotency from early development to adulthood. Recent evidence suggests that chemokine receptors are constitutively expressed by NSCs and are directly involved in stem cell biology. As cell surface receptors, chemokine receptors also provide an important avenue to enrich these cells and further identify the potential molecular pathways required to maintain their biological functions. Here, I describe in vitro methods that have been widely applied to sort, culture, maintain, and di...

Bronchopulmonary dysplasia (BPD), the chronic lung disease (CLD) in the neonate described over 40 years ago, remains a major cause of morbidity and mortality. Because of advances in perinatal care, the disease now appears in infants that are far more immature than in 1967. Soon, infants born at the limit of viability (based on the developmental stage of the lung and its actual incapacity to exchange oxygen and carbon dioxide) will be routinely resuscitated. Neonatologists will then be confronted with new dilemmas (predicting viability) and new therapeutic opportunities. This review takes a quick look at past achievements t...
