Researchers at the University of California, Santa Cruz, have identified a key molecule for establishing blood stem cells in their niche within the bone marrow. The findings, reported in the January issue of Cell Stem Cell, may lead to improvements in the safety and efficiency of bone marrow transplants. Bone marrow transplants are a type of stem cell therapy used to treat cancers such as lymphoma and leukemia and other blood-related diseases. In a bone marrow transplant, the "active...

Identification of a molecular communications pathway that influences the mobilization of hematopoietic (blood) stem cells could lead to targeted therapies for improving bone marrow transplant success rates. In a bed-side to bench approach, researchers at Cincinnati Children's Hospital Medical Center report Sept. 26 in Nature Medicine that pharmacological inhibition of a signaling pathway triggered by Egfr (epidermal growth factor receptor) increased the mobilization of hematopoietic stem...

A study led by a researcher at Albert Einstein College of Medicine of Yeshiva University has revealed a unique "partnership" between two types of bone marrow stem cells, which could lead to advances in regenerative medicine. The aim of regenerative medicine is to enable the body to repair, replace, restore or regenerate damaged or diseased cells, tissues and organs. The study was led by Paul Frenette, M.D., the new director of the Ruth L. and David S. Gottesman Institute for Stem Cell and...

Understanding how blood stem cells are maintained within the niche offers new opportunities to exploit them therapeutically Hematopoietic stem cells (HSCs) have two unique abilities that are prized by medical researchers: to self-renew and to develop into any kind of blood cell, which enables them to replenish the entire blood and immune system. Scientists have traced these qualities to a distinct locale or niche within the bone marrow that HSCs home in on, but the identity and function of...

Investigators have identified a new mechanism that controls the number of hematopoietic stem cells "“ cells that give rise to all blood and immune system cells. In a report in the online Early Edition of Proceedings of the National Academy of Sciences, researchers from Massachusetts General Hospital (MGH) and the Harvard Stem Cell Institute identify a tiny RNA molecule that increases the number of these blood stem cells, an advance that may improve treatment of blood system cancers....

Finding is important for diagnosis and treatment of cancer and anemia Hematopoietic stem cells provide the body with a constant supply of blood cells, including the red blood cells that deliver oxygen and the white blood cells that make up the immune system. Hematopoietic"”or blood"”stem cells must also make more copies of themselves to ensure that they are present in adequate numbers to provide blood throughout a person's lifetime, which means they need to strike a delicate...

p53 loss promotes acute myeloid leukemia by enabling aberrant self-renewal of myeloid precursors New research by scientists at Cold Spring Harbor Laboratory (CSHL) has illuminated in fine detail one of the genetic paths that leads to a particularly aggressive form of leukemia. CSHL Professor Scott W. Lowe. Ph.D., an Investigator of the Howard Hughes Medical Institute, led a team of scientists who wanted to know more about how the absence of an important tumor-suppressing protein called p53...

Most of the time, the body's blood-forming (hematopoietic) stem cells remain dormant, with just a few producing blood cells and maintaining a balance among the different types. However, invading bacteria can be a call-to-arms, awaking the sleeping stem cells and prompting them to produce immune system cells that fight the foreign organisms. The "bugler" that awakes the stem cells in this battle is gamma interferon, a front-line protein defender against bacterial infection, said researchers...
