First Evidence That Female Human Embryos Adjust The Balance Of XFri, 03 Jul 2009 14:00:00 EDTResearchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place in human female embryos prior to implantation in the womb.
New Targeted Therapy Finds And Eliminates Deadly Leukemia Stem CellsFri, 03 Jul 2009 11:00:00 EDTNew research describes a molecular tool that shows great promise as a therapeutic for human acute myeloid leukemia, a notoriously treatment-resistant blood cancer. The study describes exciting preclinical studies in which a new therapeutic approach selectively attacks human cancer cells grown in the lab and in animal models of leukemia.
Molecular Differences Found Between Embryonic Stem Cells And Reprogrammed Skin CellsFri, 03 Jul 2009 08:00:00 EDTResearchers have found that embryonic stem cells and skin cells reprogrammed into embryonic-like cells have inherent molecular differences, demonstrating for the first time that the two cell types are clearly distinguishable from one another.
New Connection Between Cancer Cells, Stem CellsThu, 02 Jul 2009 11:00:00 EDTA 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. The unexpected finding may lead to new anticancer therapies and a greater understanding of how adult and embryonic stem cells divide and specialize.
Alzheimer's Symptoms Reversed: Blood Stem Cell Growth Factor Reverses Memory Decline In MiceThu, 02 Jul 2009 08:00:00 EDTA human growth factor that stimulates blood stem cells to proliferate in bone marrow reverses memory impairment in mice genetically altered to develop Alzheimer's disease, a new study finds.
