stem cells
Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility.
Nobody likes Mondays. Here is some cancer news to lift your mood.
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) have discovered a key switch that makes stem cells turn into the type of muscle cells that reside in the wall of blood vessels.
President Obama will sign an executive order Monday lifting limits on human embryonic stem cell research and will direct federal agencies to "restore scientific integrity" to decision-making, White House aides said Sunday.
Obama's order follows years of wrangling over stem cells and scientific decision-making in the Bush administration.
Tampa, FL (July 1, 2009) -- A human growth factor that stimulates blood stem cells to proliferate in the bone marrow reverses memory impairment in mice genetically altered to develop Alzheimer's disease, researchers at the University of South Florida and James A. Haley Hospital found.
STANFORD, Calif. -- A molecule called telomerase, best known for enabling unlimited cell division of stem cells and cancer cells, has a surprising additional role in the expression of genes in an important stem cell regulatory pathway, say researchers at the Stanford University School of Medicine.
The joint research, funded by the National Multiple Sclerosis Society and the UK MS Society as well as the National Institutes of Health and Howard Hughes Medical Institute, was conducted by scientists at the University of California San Francisco (UCSF) and University of Cambridge and was published today (01 July) in the journal Genes and Development.
The Stowers Institute's Xie Lab has revealed how the BAM protein affects germline stem cell differentiation and how it is involved in regulating the quality of stem cells through intercellular competition. The work was published today by PNAS Early Edition.
PHILADELPHIA - Understanding the molecular signals that guide early cells in the embryo to develop into different organs provides insight into ways that tissues regenerate and how stem cells can be used for new therapies.
Cancer patients often suffer from severe pain that cannot be effectively treated with conventional medication. Researchers at the Pharmacology Institute of the University of Heidelberg have found the possible reasons for this -- tumors release two signal substances that make nerve cells especially sensitive and enhance tumor growth.
Investigators at Children's Hospital Oakland Research Institute, Oakland, California found a way to obtain large numbers of hematopoietic stem cell from human term placenta.
A study conducted by Children's Hospital & Research Center Oakland is the first to reveal a new avenue for harvesting stem cells from a woman's placenta, or more specifically the discarded placentas of healthy newborns. The study also finds there are far more stem cells in placentas than in umbilical cord blood, and they can be safely extracted for transplantation.
NEW YORK (June 22, 2009) -- New research shows that physicians failed to report clinically significant abnormal test results to patients -- or to document that they had informed them -- in one out of every 14 cases of abnormal results. In some medical groups, the failure rate is close to zero; in others it is as high as one in four abnormal results.
SINGAPORE and DURHAM, N.C. -- In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor.
Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies.
