Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments
UC Irvine School of Medicine researchers have discovered how new neurons born from endogenous neural stem cells are sent to regions of the brain where they can replace old and dying cells, a finding that suggests how stem cell therapies can be specifically targeted to brain regions affected by neurodegenerative diseases or by stroke. view more (2005-06-24)
Clinical trial to test stem cell approach for children with brain injury
A unique clinical trial will gauge the safety and potential of treating children suffering traumatic brain injury with stem cells derived from their own bone marrow starting early next year. view more (2005-12-21)
Columbia University Medical Center researchers discover potential mechanism for tumor growth
Researchers at Columbia University Medical Center have identified an inherent feature of stem and progenitor cells that may promote initiation and progression of cancerous tumors. view more (2005-12-16)
Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells-delivering anti-cancer drugs to cancer cells. view more (2006-12-26)
Mutation in blood stem cells provides clues to cancer development
The discovery suggests that development of a very specific inhibitor at the stem-cell level, to interfere with the pathway leading to the disease, could improve treatment for the cancer-causing disorder. view more (2006-04-07)
Life-threatening lupus responds to stem cell transplant therapy
Transplanting patients with blood stem cells that originate from their own bone marrow can induce the remission of life-threatening, treatment-resistant lupus. view more (2006-02-01)
First Parkinson's Gene Therapy Patient Passes One Year
The first ever patient to have undergone gene therapy for Parkinson's appears to have come through phase I without a hitch, suggesting that the therapy is safe and effective, reports Marina Murphy in Chemistry & Industry. view more (2004-09-02)
Drug has ability to cure type of leukemia
In people with chronic myeloid leukemia (CML), the drug Imatinib has been shown to drive cancer into remission, but the disease often returns when treatment is stopped. view more (2007-10-03)
HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system. view more (2006-08-14)
Fertility hope as study shows eggs survive in older ovaries
In research that could have broad implications for women's fertility treatments, scientists have found that despite their age, female mice have a renewable egg supply in their ovaries. view more (2006-07-06)
Transplanted brain cells hold promise for Parkinson's disease
Transplanted neural stem cells hold promise for reducing the destruction of dopaminergic cells that occurs in Parkinson's disease and for replacing cells lost to the disease, scientists say. view more (2006-12-05)
MIT creates 3-D scaffold for growing stem cells
Stem cells grew, multiplied and differentiated into brain cells on a new three-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system. view more (2006-12-27)
MiRNA Fingerprint Identified in Platelet Formation
Scientists have identified a handful of microRNAs (miRNAs) that appear to play a significant role in the development of platelets - blood cells critical to the body's ability to form clots following an injury. view more (2006-03-17)
New research could help us deliver genes for new bone formation
UK scientists are working on new methods to regenerate cartilage and bone by delivering genes to stem cells within the body to instruct them to turn into bone cells. view more (2005-09-29)
Jefferson researchers uncover genetic signature that predicts colon cancer
Researchers at Jefferson Medical College in Philadelphia have uncovered a genetic "signature" that accurately identifies colon cancer-a key, they hope, to better understand how the cancer develops. view more (2006-04-05)
Novel molecular 'signature' marks DNA of embryonic stem cells
A team of scientists announced today a critical step on the path of realizing the promise of embryonic stem (ES) cells for medicine. view more (2006-04-21)
Scientists use stem cells to grow cartilage
Scientists from Imperial College London have successfully converted human embryonic stem cells into cartilage cells, offering encouragement that replacement cartilage could one day be grown for transplantation. view more (2005-11-17)
How does a zebrafish grow a new tail?
If a zebrafish loses a chunk of its tail fin, it'll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg. view more (2006-12-27)
Scientists make first step towards growing human lungs for transplant
Scientists have successfully converted human embryonic stem cells into lung cells, taking a first step towards building human lungs for transplantation. view more (2005-08-23)
Prozac's target revealed
Researchers at Cold Spring Harbor Laboratory on Long Island have identified which among several different kinds of cells in the brain is the chief target of the widely prescribed antidepressant Prozac. view more (2006-05-16)
