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.

Pre-mRNA that codes for inflammatory protein identified

In a discovery that upends a longstanding tenet of human biology, University of Utah School of Medicine researchers have shown that a key process in gene regulation can occur in human platelets, unique cells that are unusual because they don't have a nucleus (anucleate).

Alternative to Cox II inhibitors

After the failure of cox II inhibitors such as Vioxx, osteoarthritis patients and their doctors are faced with a lack of alternative therapies. The Orthokine-therapy means knee-injections of IL-1Ra protein, obtained from the patient's blood.

Australian scientists rejuvenate the immune systems of mice and humans using a common hormone

The scientists, led by Associate Professor Richard Boyd and Dr Jayne Sutherland from the Monash Immunology and Stem Cell Laboratories, have revitalised the thymus which produces the T cells required to fight infection but which shuts down from early adulthood.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

MicroRNAs play an important role in regulating oogenesis

Researchers at Northwestern University and Carnegie Mellon University have found that a recently described class of molecules called microRNAs (miRNAs) play an important role in regulating oogenesis, the process by which females make eggs.

Dolly the sheep, and now Snuppy the puppy - what's next?

Since the first animal, Dolly the sheep, was cloned in 1996, scientists been able to clone pigs, cattle, mice, rabbits, horses and cats.

Bone marrow-derived cells fail to meet high expectations says Bonn study

Adult stem cells taken from bone marrow are the "shooting stars" of their field. Many research scientists have been speculating that the cells might be able to pass through the blood into diseased organs and replace defective tissue. Such cells are seen as the potential key to the treatment of certain muscle diseases.

Study addresses critical GVHD complication - limitations of bone marrow transplants

Together with 16 other institutions in the United States, University of Minnesota researchers led the largest study to date in patients with leukemia and related disorders undergoing bone marrow transplantation from unrelated donors.

Bioheart granted patent for inducing angiogenesis by electrical stimulation

Bioheart has announced that the U.S. Patent and Trademark Office issued the company a notice of allowance regarding its patent application 09/858,046, entitled Method For Inducing Angiogenesis By Electrical Stimulation of Muscles.

2 Aug 2005

Discovery may lead to new therapies for leukemia

Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow.

2 Aug 2005

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

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.

27 Jul 2005

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.

26 Jul 2005

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.

26 Jul 2005

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.

25 Jul 2005

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.

21 Jul 2005

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.
