Dr. Karen Aboody estimates that she has cured several hundred mice of a cancer of the central nervous system called neuroblastoma.
First she injected them with specialized neural stem cells that naturally zero in on the tumors and surround them. Then she administered an anti-cancer agent that the cells converted into a highly toxic drug (…)
For 3 1/2 years, the agency focused on the basic groundwork needed to someday use human embryonic stem cells to replace body parts damaged by injury or disease. Such cures are still far in the future.
Now the institute has a more immediate goal: boosting therapies
For the first time, researchers at Brigham and Women’s Hospital (BWH) have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung including bronchioles, alveoli and pulmonary vessels. This research is published in the May 12, 2011 issue of the New England Journal of Medicine.
“This research describes, for the first time, a true human lung stem cell. The discovery of this stem cell has the potential to offer those who suffer from chronic lung diseases a totally novel treatment option by regenerating or repairing damaged areas of the
I just had a birthday, and to honor such occasions, my sister always gives me silver. Not just any silver: It’s our parents’ simple wedding flatware pattern, which Margaret collects for me, one piece at a time. Over the years that the slender boxes have appeared, I’ve wondered if any of it is from the full service for 12 that I pulled in a suitcase through Manhattan’s Diamond District and sold one dreadful day 25 years ago.
It had been my assignment to sell it —- that, and a ring of Margaret’s, one of mine and, right off our mother’s
Biological sciences major Adam Reese may have found the key to keep fat cells from forming.
The University of Delaware junior believes he has identified the trigger that turns a stem cell into a fat cell. Located on the surface of cells, the trigger — a protein called endoglin — regulates what type of cell an existing stem cell will become.
Working in the UD Department of Biological Sciences‘ laboratory of cellular signaling and dynamics with assistant professor Anja Nohe, Reese investigates ways to combat osteoporosis. His findings may also have implications for obesity.
Patients afflicted with osteoporosis lose bone mass as
Expanding on previous research providing proof-of-principle that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers has now demonstrated that these cells can actually attack HIV-infected cells in a living organism.
The study, published April 12 in the journal PLoS Pathogens, demonstrates for the first time that engineering stem cells to form immune cells that target HIV is effective in suppressing the virus in living tissues in an animal model, said lead investigator Scott G. Kitchen, an assistant professor of medicine in the division of hematology and oncology at the David Geffen School of
