stem cells
Sharing the fruits of research in the biomedical sciences is critical for the advance of knowledge, yet with the advent of large-scale data gathering following the completion of the genome projects this is becoming harder to facilitate and more difficult to monitor, as reported in Nature today.
NEW YORK -- A new type of stem cell discovered in the prostate of adult mice can be a source of prostate cancer, according to a new study by researchers at the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center and NewYork-Presbyterian Hospital.
JACKSONVILLE, Fla. -- Scientists at the Mayo Clinic campus in Florida have found that the lung cancer oncogene PKCiota is necessary for the proliferation of lung cancer stem cells. These stem cells are rare and powerful master cells that manufacture the other cells that make up lung tumors and are resistant to chemotherapy treatment.
A new study finds substantial improvement in a mouse model of a rare, hereditary neurodegenerative disease after transplantation of normal human neural stem cells.
CLEMSON -- An injectable biomaterial gel may help brain tissue grow at the site of a traumatic brain injury, according to findings by a Clemson
University bioengineer.
A key compound resupplies bone marrow with fast-acting stem cells that can more quickly rekindle blood cell production, according to a study published online today in the journal Blood. While the study was in mice, in the study authors say it has the potential to increase survival among patients with life-threatening blood cell shortages.
KANSAS CITY, MO -- September 1, 2009 -- New research on traumatic brain injury (TBI) is being presented this week at the Military Health Research Forum (MHRF), a scientific meeting hosted by the Department of Defense (DOD) Congressionally Directed Medical Research Programs (CDMRP). Service men and women are particularly susceptible to TBI given the nature of combat.
DALLAS -- Sept. 1, 2009 -- A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.
Barcelona, Spain, 31 August: Obesity is one of the most important health problems in industrialized countries irrespective of socio-economic status, age, sex or ethnicity. The prevalence of childhood obesity in children has reached alarming levels, even in developing countries.
University Park, Pa. -- Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.
SEATTLE -- Scientific dogma has long asserted that females are born with their entire lifetime's supply of eggs, and once they're gone, they're gone. New findings by researchers at Fred Hutchinson Cancer Research Center, published online Aug.
Scientists in Switzerland have discovered a way to block the growth of human colon cancer cells, preventing the disease from reaching advanced stages and the development of liver metastases.
MADISON -- A team of scientists from the University of Wisconsin-Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells -- suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.
BOSTON--Two of the most powerful approaches to cancer treatment -- a stem cell transplant and an immune system-stimulating vaccine -- appear to reinforce each other in patients with an aggressive, hard-to-control form of leukemia, Dana-Farber Cancer Institute scientists have found.
