For the first time, scientists have shown that amniotic fluid (the protective liquid surrounding an embryo) may be a potential new source of stem cells for therapeutic applications. The study was prepublished online on February 12, 2009, in Blood, the official journal of the American Society of Hematology. "Building on observations made by other scientists, our research team wondered whether stem cells could be detected in amniotic fluid. We looked at the capacity of these cells to form new...

Using a mouse model of human leukemia, researchers have unlocked more information about the genetic factors related to the generation and maintenance of leukemia stem cells. The discovery is likely to have profound impact on how future therapy can be designed to target cancer stem cells. Leukemia stem cells (LSCs) were initially described as rare cells that share characteristics with normal hematopoietic stem cells (HSCs). HSCs are known as partially committed adult stem cells that can give...

Stem cells of any kind are defined by their eternal nature, reproducing themselves and providing a pool of cells from which more differentiated tissues arise.Now a group of researchers from Baylor College of Medicine in collaboration with researchers in Australia and the United Kingdom, demonstrate that two specific "sister" genes that control transcription play often overlapping roles in maintaining this pool of hematopoietic or blood cell-forming stem cells.Redundant rolesIn a report in the...

By using OP9-DL1 cells as a support system, researchers can study the differentiation of embryonic stem cells into mature components of the immune system. This month's issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc2_09.dtl) features a set of methods from Juan Carlos Zúñiga-Pflcker's laboratory at the University of Toronto (http://www.immunology.utoronto.ca/faculty/directory/zunigapflucker.htm) detailing "The OP9-DL1 System:...

 A new study sheds light on a little understood biological process called quiescence, which enables blood-forming stem cells to exist in a dormant or inactive state in which they are not growing or dividing. According to the study's findings, researchers identified the genetic pathway used to maintain a cell's quiescence, a state that allows bone marrow cells to escape the lethal effects of standard cancer treatments.Researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) found...

A type of stem cell responsible for all blood and immune system cells reproduces much more slowly than expected. Using this subpopulation of hematopoietic stem cells may help treatment of leukemia and other marrow-based diseases by improving the outcome of stem cell transplants, also referred to as bone marrow transplants. The entire population of hematopoietic stem cells (HSCs) in bone marrow are believed to reproduce at a rate of about 7 percent per day, with each cell dividing every two...

BOTHELL, Wash., Dec. 29 /PRNewswire-FirstCall/ -- CellCyte Genetics Corporation (CellCyte) (OTC Bulletin Board: CCYG) reports that a December 24, 2008 article published by the Seattle Times reporting on CellCyte's third quarter 2008 SEC 10Q filing incorrectly reported that CellCyte 'closes.' In CellCyte's August 14, 2008 press release, the Company reported progress in its bioreactor business segment and generally described its development plan to commercialize its bioreactor product line....

 Using stem cell lines not typically combined, researchers at Columbia University Medical Center have designed a new way to "grow" bone and other tissues.The inability to foster angiogenesis "“ a physiological process involving the growth of new blood vessels from pre-existing vessels "“ has been a major roadblock in tissue regeneration. Previous approaches have included the use of angiogenic growth factors and the fabrication of artificial blood vessels. However, there are...

Investigators from Massachusetts General Hospital (MGH) have found a subpopulation of hematopoietic stem cells, the source of all blood and immune system cells, that reproduce much more slowly than previously anticipated. Use of these cells may improve the outcome of stem cell transplants "“ also called bone marrow transplants "“ for the treatment of leukemia and other marrow-based diseases. The report will appear in the journal Nature Biotechnology and is being released online to...
