Stem Cells News and Research

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.

Revolutionary finding on female reproductive function

Previously unrecognized stem cells found in the bone marrow and blood of mice can "restock" a depleted ovary with new egg cells within weeks, according to new research published in this week's issue of the journal Cell.

Breakthrough in stem cells research with pigs - exciting news for heart patients

In exciting news for heart patients, researchers say they have successfully used stem cells to treat heart attack tissue damage in pigs.

New chemical compound can accelerate stem cell mobilization

The finding has led to the development of a new chemical compound that can accelerate this process (called stem cell mobilization) in mice - which could eventually lead to more efficient stem cell harvesting for human use.

Nerve-insulating substance called myelin can lead to functional improvements in animals with spinal cord injury

Combining partially differentiated stem cells with gene therapy can promote the growth of new "insulation" around nerve fibers in the damaged spinal cords of rats, a new study shows.

Single protein regulates secretion levels - helps stem cells become secretory cells

Johns Hopkins researchers have discovered that a single protein regulates secretion levels in the fruit fly's salivary gland and its skin-like outer layer.

Stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs

In just two months, stem cells harvested from another pig's bone marrow and injected into the animal's damaged heart restored heart function and repaired damaged heart muscle by 50 percent to 75 percent.

Does the heart contain stem cells that are self-renewing?

If you've ever used a loofah in the shower, you've stirred up some stem cells. As the outer layer of skin sloughs off, stem cells in the dermis rush to repair and replace those buffed away.

Engineered tissue is more viable with blood of its own

By adding small blood vessels to artificially grown muscle tissue, the chances of succesful tissue 'repair' rise. Without nourishing blood, thicker tissue has limited viability.

Australian stem cell discovery hailed as a major medical and scientific development

Monash Institute of Medical Research (MIMR) senior scientist Dr Caroline Gargett's discovery of adult stem cells in the uterus that can be grown into bone, muscle, fat and cartilage, has been hailed as a major medical and scientific development by international reproduction experts.

Major stem cell discovery

Research published in Nature tomorrow (21 July) will outline for the first time the stem cell origin of the structure of the neck and shoulders in vertebrates.

SIRT1 gene suppresses longevity

Researchers have determined that a gene present in mouse cells limits the number of times that a cell can divide. The gene is involved in a process, called senescence, which is thought to ensure that aging cells do not pass on harmful mutations.

Researchers have identified a protein that is crucially involved in how our memories are stored and processed

University of Queensland researchers have identified a protein that is crucially involved in how our memories are stored and processed, paving the way for new strategies to treat conditions certain mental disorders.

New theory on aging says popping pills and drinking orange juice no guarantee you'll live longer

In direct contrast to previous reports, researchers now say that drinking gallons of orange juice and popping vitamin pills may not be a guarantee that you will live longer.

Ethical guidelines suggested for stem cell research in primates

Before conducting research that involves putting human stem cells into the brains of nonhuman primates such as monkeys or apes, scientists and oversight committees should consider a series of ethical criteria, according to a policy paper released in the July 15 issue of Science.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Experts discuss use of human stem cells in ape and monkey brains

An expert panel of stem cell scientists, primatologists, philosophers and lawyers has concluded that experiments implanting, or grafting, human stem cells into non-human primate brains could unintentionally shift the moral ground between humans and other primates.

Transplanted neural stem cells may serve not only as replacement cells for tissue repair, but in some circumstances may also protect the brain from inflammation

Researchers at the San Raffaele Hospital (Milan, Italy) published unexpected results of studies in which immature nerve cells (adult mouse neural stem cells) injected into the blood of mice with MS-like disease were able to suppress the immune attacks that damage the brain and spinal cord tissues.

Outer lining of the umbilical cord is a rich source of stem cells

CellResearch Corporation in Singapore and its team of scientists, headed by Chief Scientist, Dr Phan Toan Thang, have recently made a revolutionary discovery: that the outer lining of the umbilical cord is a rich source of stem cells.
