Alzheimer’s disease potential treatment from neural stem cells

Frank LaFerla, left, Mathew Blurton-Jones and colleagues found that neural stem cells could be a potential treatment for advanced Alzheimer's disease

UC Irvine scientists have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer’s disease, raising hopes of a potential treatment for the leading cause of elderly dementia that afflicts 5.3 million people in the U.S.

Mice genetically engineered to have Alzheimer’s performed markedly better on memory tests a month after mouse neural stem cells were injected into their brains. The stem cells secreted a protein that created more neural connections, improving

Fight baldness using Stem Cells

Baldness is an undesirable condition that afflicts both men and women, many of which have family members with significant hair loss. According to Health Day News, a new study of stem cells in mice shows promise for future treatments for people who battle hair loss.

The study was conducted on the fatty skin layers of mice by researchers at Yale University. Specifically, adipose precursor cells were found to spur new hair growth in mice, according to Health Day News.

Stem cells are present in hair follicles, which help generate hair growth. Health Day News explains that these cells are still present

Correcting Sickle Cell Disease With Stem Cells

Using a patient’s own stem cells, researchers at Johns Hopkins have corrected the genetic alteration that causes sickle cell disease (SCD), a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene.

The research team cautions that the work, done only in the laboratory, is years away from clinical use in patients, but should provide tools for developing gene therapies for SCD and a variety of other blood disorders.

Scientists watch stem cells at work regenerating tissue

Scientists have for the first time watched and manipulated stem cells as they regenerate tissue in an uninjured mammal, Yale researchers report July 1 online in the journal Nature.

Using a sophisticated imaging technique, the researchers also demonstrated that mice lacking a certain type of cell do not regrow hair. The same technique could shed light on how stem cells interact with other cells and trigger repairs in a variety of other organs, including lung and heart tissue.

“This tells us a lot about how the tissue regeneration process works,” said Valentina Greco, assistant professor of genetics and of dermatology at

Rutgers Team Discovers Novel Approach to Stimulate Immune Cells

Researchers at Rutgers University have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance.

Dipak Sarkar, professor in the Department of Animal Sciences at the Rutgers School of Environmental and Biological Sciences and his research team have been able to take a new pharmacological approach to activate the immune cells to prevent cancer growth through stimulation of the opiate receptors found on immune cells.

This research, funded by the National Institutes of Health-National Institute on Alcohol Abuse and Alcoholosm, is featured on the cover of the May 11 issue of the Journal
