New research findings in 25 presentations Researchers from Seidman Cancer Center at University Hospitals (UH) Case Medical Center and Case Western Reserve University School of Medicine presented new research findings in 25 presentations this weekend at the 53rd Annual Meeting of the American Society of Hematology (ASH) at the San Diego Convention Center. "The breadth and depth of this innovative cancer research presented at ASH is truly outstanding," says Stan Gerson, MD, Director of...

Penn Study Unlocks Origins of Blood Stem Cells

A research team led by Nancy Speck, PhD, professor of Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, has discovered a molecular marker for the immediate precursors of hematopoietic (blood) stem cells (HSCs) in the developing embryo, which provides much-needed insights for making these cells from engineered precursors. Because HSCs, found in the bone marrow of adult mammals, generate all of the blood cell types of the body, unlocking the...

Human stem cells aren't immune to the aging process, according to scientists at the Stanford University School of Medicine. The researchers studied hematopoietic stem cells, which create the cells that comprise the blood and immune system. Understanding when and how these stem cells begin to falter as the years pass may explain why some diseases, such as acute myeloid leukemia, increase in prevalence with age, and also why elderly people tend to be more vulnerable to infections such as colds...

Stromal cells, as distinct from hematopoietic cells, are an essential component of the bone marrow microenvironment and are necessary for the long-term maintenance of hematopoietic stem cells (HSCs) in vitro. Previous studies have shown that stromal cells regulate the proliferation and differentiation of HSCs through the production of diffusible hematopoietic regulatory factors and extracellular matrix, and through physical cell-cell interactions involving adhesion molecules and gap...

Scientists Successfully Expand Bone Marrow-derived Stem Cells In Culture

  All stem cells–regardless of their source–share the remarkable capability to replenish themselves by undergoing self-renewal. Yet, so far, efforts to grow and expand scarce hematopoietic (or blood-forming) stem cells in culture for therapeutic applications have been met with limited success. Now, researchers at the Stowers Institute for Medical Research teased apart the molecular mechanisms enabling stem cell renewal in hematopoietic stem cells isolated from mice and...

For the first time, researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic stem cells (HSCs) into a human donor, according to study results published today in Blood, the Journal of the American Society of Hematology (ASH). As the global need for blood continues to increase while the number of blood donors is decreasing, these study results provide hope that one day patients in need of a blood transfusion might become their own donors. Using...

(Ivanhoe Newswire) -- New research finds that growing blood stem cells in the laboratory for about a week may help to overcome one of the most difficult roadblocks to successful transplantation, immune rejection. The study may lead to more promising therapeutic strategies for transplanting blood stem cells. Hematopoietic stem cells (HSCs) are cells that can give rise to all of the different types of blood cells. Transplantation of HSCs has been used to treat leukemia, lymphoma, and other...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
