Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

No significant difference in patient outcomes with RBC transfusions using lower threshold levels

The level at which red blood cells are transfused, a common treatment in clinical practice, is often deliberated among physicians. Guidelines for blood transfusion levels were only recently issued in March 2012 diminishing some of the debate. Today, in a new section called JAMA Clinical Evidence Synopsis, the Journal of the American Medical Association (JAMA), published a summary of the systematic review of the 19 clinical trials that compare higher versus lower hemoglobin thresholds in red blood cell transfusion.

Regenerative medicine: an interview with Christophe Dardel, President of DSM Biomedical

Regenerative medicine is a new, exciting field that is based upon the belief that the human body has the inherent power to heal itself, but in some instances it just needs a little help.

Broader criteria for background checks can help prevent firearm violence

Garen Wintemute, a leading authority on gun violence prevention and an emergency medicine physician at UC Davis, believes broader criteria for background checks and denials on gun purchases can help prevent future firearm violence, including mass shooting catastrophes such as those that occurred at Sandy Hook, Aurora, Virginia Tech and Columbine.

New light on how epigenetic signals may function together to determine fate of stem cell

Long-standing research efforts have been focused on understanding how stem cells, cells capable of transforming into any type of cell in the body, are capable of being programmed down a defined path to contribute to the development of a specific organ like a heart, lung, or kidney. Research from the University of North Carolina at Chapel Hill School of Medicine has shed new light on how epigenetic signals may function together to determine the ultimate fate of a stem cell.

Researchers reveal critical role of BRCA1 gene in maintenance of hair follicle stem cells

Our DNA, which stores our genetic information, is constantly submitted to damage. If not properly repaired, DNA damage can lead to cell death, which may in turn lead to tissue exhaustion and ageing, or induce mutations resulting in uncontrolled cell proliferation and cancer. Brca1 is a key gene that mediates DNA repair. Mutations in Brca1 lead to familial and sporadic breast and ovarian cancer in humans.

Cancer-associated inflammation boosts ADAR1 enzyme activity

An international team, headed by researchers at the University of California, San Diego School of Medicine, has identified a key enzyme in the reprogramming process that promotes malignant stem cell cloning and the growth of chronic myeloid leukemia (CML), a cancer of the blood and marrow that experts say is increasing in prevalence.

OncoMed commences dosing in OMP-52M51 Phase 1 clinical trial for hematologic cancers

OncoMed Pharmaceuticals, Inc., a clinical-stage company developing novel therapeutics that target cancer stem cells (CSCs), or tumor-initiating cells, today announced that patient dosing has begun in a Phase 1 clinical trial of OMP-52M51 in patients with hematologic cancers.

New technique may prevent inheritance of mitochondrial diseases in children

A joint team of scientists from The New York Stem Cell Foundation (NYSCF) Laboratory and Columbia University Medical Center (CUMC) has developed a technique that may prevent the inheritance of mitochondrial diseases in children.

Study shows how to prod stem cells to become 2 different types of blood vessel tissues

Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.

Oscillation of gene activity may underlie how embryos grow in proportion

From a single-cell egg to a fully functional body: as embryos develop and grow, they must form organs that are in proportion to the overall size of the embryo. The exact mechanism underlying this fundamental characteristic, called scaling, is still unclear. However, a team of researchers from EMBL Heidelberg is now one step closer to understanding it.

Study examines role of race and ethnicity in stem cell donation

New research examining the role of race and ethnicity in an individual's decision to become a donor for hematopoietic cell transplantation (HCT) identifies several factors associated with varied participation rates in national donor registries across racial/ethnic groups. Results of this first-of-its-kind study are published online today in Blood, the Journal of the American Society of Hematology (ASH).

New work on Akt's role in cancer stem cell biology

The protein kinase Akt is a key regulator of cell growth, proliferation, metabolism, survival, and death. New work on Akt's role in cancer stem cell biology from the lab of senior author Honglin Zhou, MD, PhD and Weihua Li, co-first author, both from the Center for Resuscitation Sciences, Department of Emergency Medicine, Perelman School of Medicine, University of Pennsylvania, and Xiaowei Xu, Department of Pathology and Laboratory Medicine, appears in Molecular Cell.

Study examines five varieties of cells after transplantation in the CNS

When different types of cells are transplanted with the intent of having them aid in repairing central nervous system (CNS) trauma, what is the fate and function of those cells? A Belgian research team carried out research aimed at answering this question by determining how five varieties of cells - neural stem cells, mouse embryonic fibroblasts, dendritic cells, bone marrow mononuclear cells (BMMNCs) and splenocytes - functioned and survived after transplantation in the CNS.

Two recent experimental treatments improve visual function in mouse models of retinitis pigmentosa

Two recent experimental treatments - one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy - have been shown to produce long-term improvement in visual function in mouse models of retinitis pigmentosa (RP), according to the Columbia University Medical Center (CUMC) scientists who led the studies. At present, there is no cure for RP, the most common form of inherited blindness.

New clues in understanding how epithelial cells repair themselves following chlorine-related injury

Scarring of the airways can lead to long-term breathing problems for some people exposed to high levels of chlorine gas from events such as an industrial accident, chemical spill following a train derailment or terroristic chemical warfare. Household mishaps from mixing bleach with acidic cleaning products also can cause release of chlorine gas; if this occurs in a poorly ventilated space, chlorine levels could be high enough to cause lung injury.

Lou Gehrig's disease may be treatable using neural stem cells

Promising new research provides evidence that ALS, amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, may be treatable using neural stem cells.

Umbilical cord stem cell therapy shows promise in infant BPD

Researchers have successfully used human umbilical cord stem cells to partially prevent damage and restore lung structure and function in an experimental animal model of bronchopulmonary dysplasia.

The association alfa-enolase/plasmin is a new selective target for treating muscular pathologies

Researchers at the Bellvitge Biomedical Research Institute (IDIBELL) have described a new selective target in muscle regeneration. This is the association of alpha-enolase protein and plasmin.

Viewpoints: Raising Medicare's entitlement age doesn't save money; New anti-fraud efforts

Looking for ways to slow the growth of entitlement programs, budget negotiators in Washington are considering making seniors wait two years longer to qualify for Medicare - from age 65 to 67. Many Republicans have endorsed the idea, noting that Medicare beneficiaries now live far longer on average than they did when Congress created the program in 1965.
