Improved Understanding Of Niche Control Of Stem Cell FunctionThe Stowers Institute's Xie Lab has published findings that begin to characterize the poorly understood interaction among stem cells within their cellular microenvironment, called a niche.The findings appear in Cell Stem Cell.The Xie Lab demonstrated that differentiation-defective Drosophila ovarian germline stem cells (GSCs), behaving like human cancer stem cells, can out-compete normal stem cells for a position in the niche.Advanced Cell Technology Announces Creation Of Human Embryonic Stem Cell Lines Without The Destruction Of EmbryosAdvanced Cell Technology, Inc. (OTC Bulletin Board: ACTC) together with colleagues announced today the development of five human embryonic stem cell (hESC) lines without the destruction of embryos. These new results have the potential to end the ethical debate surrounding the use of embryos to derive stem cells. In fact, the NIH report to the President refers to this technology as one of the viable alternatives to the destruction of embryos.New Insight Into Factors That Drive Muscle-Building Stem CellsA report in the January issue of Cell Metabolism, a publication of Cell Press, provides new evidence explaining how stem cells known as satellite cells contribute to building muscles up in response to exercise. These findings could lead to treatments for reversing or improving the muscle loss that occurs in diseases such as cancer and AIDS as well as in the normal aging process, according to the researchers.DomaniCell's Unique CGMP And Hospital-based Cord Blood Program ExpandsDomaniCell, LLC (DomaniCell), a leading service provider in the field of stem cell collection and storage, announced that Saint Peter's University Hospital has recently partnered with DomaniCell to provide a hospital-based cord blood banking program.Scientists Urge Embryonic Stem Cell Research; Despite New Technique Creating Embryonic-Like Stem CellsAlthough some experts "hailed" the November 2007 announcement that scientists in Japan and Wisconsin had "reprogrammed" mature adult human skin cells to produce embryonic-like stem cells that might eventually be converted into heart, nerve or other tissue as the "solution" to the U.S.Differentiation Blocked In Tumor Stem CellsA new comparison of normal stem cells and cancer stem cells reveals that the cancer stem cells are abnormally trapped at an early stage of development. The research, published by Cell Press in the January issue of Cancer Cell, significantly advances the understanding of glioma pathophysiology and provides new directions for design of therapeutic strategies that are targeted to specific types of tumors.Growing Artificial Skin From Hair RootsThere is new hope for patients with chronic wounds: euroderm GmbH and the Fraunhofer Institute for Cell Therapy and Immunology IZI in Leipzig have been granted approval to produce artificial skin from patients' own cells. It sounds like something from a science fiction novel: Pluck a few of someone's hairs, and four to six weeks later they have grown into a piece of skin.
