Stem-cell therapy may provide new approach to fight infection

New Canadian study suggests commonly used type of bone marrow stem cell may be able to help treat sepsis

A new study from researchers in Ottawa and Toronto suggests that a commonly used type of bone marrow stem cell may be able to help treat sepsis, a deadly condition that can occur when an infection spreads throughout the body. The study, published in the American Journal of Respiratory and Critical Care Medicine, shows that these cells can triple survival rates in an experimental model of sepsis.

Gene regulating human brain development identified

MADISON — With more than 100 billion neurons and billions of other specialized cells, the human brain is a marvel of nature. It is the organ that makes people unique.

Now, writing in the journal Cell Stem Cell (July 1, 2010), a team of scientists from the University of Wisconsin-Madison has identified a single gene that seems to be a master regulator of human brain development, guiding undifferentiated stem cells down tightly defined pathways to becoming all of the many types of cells that make up the brain.

New research model of human prostate cancer shows cancer development

Progress toward understanding the role of sex hormones in the growth of prostate cancer—the most common cancer in U.S. men—has been hindered by the lack of a suitable laboratory research model. Now researchers say they have developed the first model of hormone-induced human prostate cancer initiation and progression.

UVA radiation damages DNA in human melanocyte skin cells and can lead to melanoma

A new study by researchers at NYU School of Medicine found that UVA radiation damages the DNA in human melanocyte cells, causing mutations that can lead to melanoma. Melanocytes, which contain a substance called melanin that darkens the skin to protect it from the ultraviolet rays of the sun, are more vulnerable to UVA radiation than normal skin cells because they are unable to repair themselves as efficiently.

Experimental nonsteroidal treatment of asthma shows promise

A new nonsteroidal, anti-inflammatory therapy made from a human protein significantly decreases disease signs of asthma in mice, opening the possibility of a new asthma therapy for patients who do not respond to current steroid treatments. Results of this therapy in an animal model were presented at The Endocrine Society’s 92nd Annual Meeting in San Diego.
