Stem cells found in adult hair follicles may provide alternative to embryonic stem cells

... rise to the autonomic and enteric nervous systems along with endocrine cells, bone and smooth muscle cells. The cells can be isolated from the hair follicle bulge as multipotent stem cells, and then expanded in culture into millions of cells without losing stem cell markers. "We grafted the cells into ...

U-M researchers use nanoparticles to target brain cancer

... Researchers incorporated a drug called Photofrin along with iron oxide into nanoparticles that would target cancerous brain tumors. Photofrin is a type of photodynamic therapy, in which the drug is drawn through the blood stream to tumor cells; a special type of laser light activates the drug to attack t...

Austin, along with colleague Indraneil Das from the Institute of Biodiversity and Environmental Conservation at the Universiti Malaysia Sarawak, will publish their findings and photos of the new species in the prestigious Journal of Herpetology. The article, which...

Edge density key to controlling gypsy moth spread

...ce data from more than 100,000 pheromone traps set along the expanding gypsy moth population front for their theoretical model. The pheromone trap data were collected from 1988 to 2004. They used a theoretical model to show how an interaction between negative population growth at low densities ?"the All...

Nanotech tools yield DNA transcription breakthrough

... breaks free from its initial binding site to move along DNA to continue synthesizing RNA. The results establish that during transcription initiation the machine remains stationary at its initial binding site and "reels in" adjacent DNA segments, unwinding these segments and pulling the unwound DNA stra...

Male circumcision reduces HIV risk, study stopped early

Human stem cells delay start of Lou Gehrig's disease in rats

...ete transplant of cells - already being planned -- along the full length of the spine to affect upper body nerves and muscles as well might lead to longer survival in the same rats. "We only injected cells in the lower spine, affecting only the nerves and muscles below the waist," he noted. "The nerve...

Abnormal overexpression of p53 is a predictive molecular biomarker

Advexin is farthest along in federal Food and Drug Administration (FDA) review of any experimental gene therapy, according to Introgen, and has been granted fast track designation for an application of use in head and neck cancer. Results from two phase II clinical trials inv...

UCLA researchers unravel a mystery about DNA

High HPV concentrations combined with smoking significantly raise risks of cervical cancer

...identified 499 women with cervical cancer in situ, along with 499 cancer-free women as controls. For these women, they compared their smoking behavior with concentrations (known as viral load) of HPV-16, the viral strain most associated with cervical cancer. The researchers found that a combination of hig...

Soil nutrition affects carbon sequestration in forests

Neural stem cells lend the brain a surprising capacity for self-repair

...self-repair and local remodeling can indeed happen along the brain's lateral ventricular wall, and further insights into this process should shed light on whether SVZ neural stem cells participate in stroke/trauma-induced brain remodeling and postnatal/adult brain tumor formation. Furthermore, understandin...
