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.

Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.

Researchers use gelation chips to develop strong muscle fibers

USC researcher Megan L. McCain and colleagues have devised a way to develop bigger, stronger muscle fibers. But instead of popping up on the bicep of a bodybuilder, these muscles grow on a tiny scaffold or "chip" molded from a type of water-logged gel made from gelatin. [More]

New IDSA guidelines focus on diagnosis, treatment of deadly aspergillosis

New therapies are improving care, but early diagnosis remains critical in the effective treatment of invasive, a potentially deadly fungal infection, according to new guidelines released by the Infectious Diseases Society of America and published in the journal Clinical Infectious Diseases. [More]
Stem cell procedure may be safe for ALS patients

Stem cell procedure may be safe for ALS patients

A phase II clinical trial in people with amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, suggests that transplanting human stem cells into the spinal cord may be done safely. [More]
Researchers devise method to identify functional contribution of SIRT6

Researchers devise method to identify functional contribution of SIRT6

The enzyme sirtuin 6, or SIRT6, serves many key biological functions in regulating genome stability, DNA repair, metabolism and longevity, but how its multiple enzyme activities relate to its various functions is poorly understood. [More]
Therapeutic stem cells exit bloodstream in different way than previously thought

Therapeutic stem cells exit bloodstream in different way than previously thought

Researchers at North Carolina State University have discovered that therapeutic stem cells exit the bloodstream in a different manner than was previously thought. This process, dubbed angiopellosis by the researchers, has implications for improving our understanding of not only intravenous stem cell therapies, but also metastatic cancers. [More]
LIF-treated muscle stem cells show promise in treatment of muscular dystrophy

LIF-treated muscle stem cells show promise in treatment of muscular dystrophy

Satellite cells are stem cells found in skeletal muscles. While transplantation of such muscle stem cells can be a potent therapy for degenerative muscle diseases such as Duchenne muscular dystrophy, these cells tend to lose their transplantation efficiency when cultured in vitro. [More]

New study shows microRNAs play important role in inducing asthma

A new study shows that microRNAs, which are small, noncoding RNA molecules that can silence genes, have an important role in inducing asthma. [More]

Scientists uncover how changes in metabolism of embryonic stem cells can help engineer new blood vessels

Researchers from the University of Illinois at Chicago College of Medicine have uncovered how changes in metabolism of human embryonic stem cells help coax them to mature into specific cell types — and may improve their function in engineered organs or tissues. [More]
Gamma-ray irradiation improves safety of stem cell transplantation in Parkinson’s disease patients

Gamma-ray irradiation improves safety of stem cell transplantation in Parkinson’s disease patients

Replacing dopamine-producing cells in the brain represents a promising therapeutic approach in Parkinson's disease, and a new study shows how post-transplantation gamma-ray irradiation can reduce the risk of tumor formation. [More]
Scientists discover how faulty genetic instructions contribute to development of AML

Scientists discover how faulty genetic instructions contribute to development of AML

Scientists have previously identified a series of genetic errors that commonly occur inside cancerous blood cells, but it hasn't been clear exactly how those genetic malfunctions create immature blood cells that overpopulate, crowd out healthy cells and spread in patients with acute myeloid leukemia or AML.
