Stem Cells News and Research

RSS

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.

Human stem cells aid stroke recovery in rats

Neural cells derived from human embryonic stem cells helped repair stroke-related damage in the brains of rats and led to improvements in their physical abilities, according to a new study by researchers at the Stanford University School of Medicine.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Major milestone in the culturing of human blood stem cells

Patients with leukemia, certain autoimmune diseases and genetic defects such as sickle-cell anemia can be treated with blood stem cells either from a donor's bone marrow or from cord blood - but the supply of effective stem cells often runs short.

New clues about how cancer cells grow

Scientists in Switzerland are uncovering new clues about how cancer cells grow - and how they can be killed - by studying stem cells, 'blank' cells that have the potential to develop into fully mature or 'differentiated' cells and other scientists in UK have made a breakthrough in understanding the cause of the most common form of childhood cancer, acute lymphoblastic leukaemia (ALL).

Researchers use embryonic stem cells to develop functioning immune system blood cells

For the first time, researchers have used embryonic stem cells to develop functioning immune system blood cells -- an important step in eventually using embryonic stem cells as an alternative source of cells for traditional bone marrow transplantations.

Australian stem cell fracture treatment shows great results

A trial at an Australian hospital using adult stem cells to repair bone fractures has had excellent results.

Discovery that embryonic stem cells can be used to create functional immune system blood cells

A new study demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells, a finding which is an important step in the utilization of embryonic stem cells as an alternative source of cells for bone marrow transplantation.

Scientists reprogram human skin cells into embryonic stem cells

UCLA stem cell scientists have reprogrammed human skin cells into cells with the same unlimited properties as embryonic stem cells without using embryos or eggs.

Release of blood stem cells from bone marrow is regulated by brain through human biological clock

These new findings, published online on the website of the journal Nature, point out that the harvest of stem cells for transplantation may be improved by timing it at the peak of their release.

Risk factors for severe RSV infection in immunocompromised children

St. Jude Children's Research Hospital investigators and collaborators have shown how to predict if a child who is infected with respiratory syncytial virus (RSV) while being treated for cancer or another catastrophic disease is at high risk for developing severe infection. The finding will help clinicians improve guidelines for managing these infected children.

Researchers identify cells that cause nervous system disease

Two teams of University of Michigan researchers have tracked down the cells responsible for neurofibromatosis type1, a disfiguring, incurable condition and one of the most common hereditary disorders.

Nano scaffold to rebuild nerve damage

A Monash University PhD student has developed a new technique that could revolutionise stem cell treatment for Parkinson's disease and spinal cord injury.

Targeting astrocytes slows progression of Lou Gehrig's disease

In what the researchers say could be promising news in the quest to find a therapy to slow the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, scientists at the University of California, San Diego (UCSD) School of Medicine have shown that targeting neuronal support cells called astrocytes sharply slows disease progression in mice.

Neurogenesis plays an important role in the acquisition and storage of spatial memory

Boosted by physical and mental exercise, neural stem cells continue to sprout new neurons throughout life, but the exact function of these newcomers has been the topic of much debate.

Porous structures help boost integration of host tissue with implants

Results published in FASEB (the journal of the Federation of American Societies for Experimental Biology) by researchers at Columbia University, including Jeremy Mao of the Columbia College of Dental Medicine, demonstrate a novel way of using porous structures as a drug-delivery vehicle that can help boost the integration of host tissue with surgically implanted titanium.

Stem cell treatment for babies with brittle bones in the womb

The extraordinary results of an in utero stem cell treatment could lead to a new treatment for babies with brittle bones, as well as a range of other disabling conditions, according to a maternal-fetal medicine researcher, now based at The University of Queensland (UQ).

Stem cell therapy studies for stroke, cerebral palsy prepare for clinical trials

Finding answers about optimal dosage and timing for stem cell therapy in adults with strokes and newborns with ischemic injuries is a goal of two new federally funded studies.

Kidney cancer drug attacks a major type of acute myeloid leukemia

A drug used to treat kidney cancer also targets a genetic mutation active in about one third of patients with acute myeloid leukemia (AML), the most common and lethal form of adult leukemia, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan. 29 edition of the Journal of the National Cancer Institute.

New nanomedicine research for prostate cancer

The Prostate Cancer Foundation, largely through the generosity of David H. Koch, has given $5 million to four institutions, including Weill Cornell Medical College, to support novel research in prostate cancer. The gift is one of the largest-ever individual donations for prostate cancer research.

New target found for asthma

An enzyme released by mast cells in the lungs appears to play a key role in the tightening of airways that is a hallmark of asthma -- pointing to a potential new target for treatment against the illness.
