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.

New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

1G8 antibody signals prostate cancer cells to stop growing and die

Researchers at UCLA's Jonsson Cancer Center have uncovered the mechanism by which an antibody blocks the growth of prostate cancer in animal models, a discovery that could pave the way for development of a new molecularly targeted therapy.

Alternative methods to create stem cells successful in mice-studies

According to researchers in the U.S. two alternative methods for making embryonic stem cells, work in mice and could lead to a less controversial way to grow them.

New public survey on stem cells

Stem cells are unique among human cells in that they possess the uncanny ability to develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits.

Natural cancer killing cells from the human embryonic stem cells

For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors).

Tissue engineering used to reconstruct defective tracheas (windpipes) in fetal lambs

Researchers at Children's Hospital Boston report using tissue engineering to reconstruct defective tracheas (windpipes) in fetal lambs, first using cells from the amniotic fluid to grow sections of cartilage tube, and then implanting these living grafts into the lambs while still in the womb.

Cells inside the hair follicle are true multipotent stem cells

Using an animal model, a research team led by Yann Barrandon at the EPFL (Ecole Polytechnique Federale de Lausanne) and the CHUV (Lausanne University Hospital) has discovered that certain cells inside the hair follicle are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement.

Immature stem cells that proliferate to form brain tissues in mice can function for at least a year

New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year -- most of the life span of a mouse -- and give rise to multiple types of neural cells, not just neurons.

Somatic adult stem cell niches - key regulators of stem cell activity in mammary tissue

Researchers at Georgetown's Lombardi Comprehensive Cancer Center have found that the onset of breast cancer may be due to defects in somatic adult stem cell niches that exist long before tumors develop.

High blood glucose levels early in pregnancy deprive the embryo of oxygen

The babies of women with diabetes are two to five times more likely to develop birth defects than offspring of women without the disease.

Ischemic brain injury - another promising avenue for stem cell therapy

Adult stem cell therapy quickly and significantly improves recovery of motor function in an animal model for the ischemic brain injury that occurs in about 10 percent of babies with cerebral palsy, researchers report.

Johns Hopkins awarded $12 million to study how stem cell therapies can be used to treat hearts damaged by heart attack

Heart specialists at Johns Hopkins Heart Institute have been awarded more than $12 million from the National Heart, Lung, and Blood Institute (NHLBI) to study how stem cell therapies can be used to treat hearts damaged by heart attack or heart failure.

Stem cells help regenerate cartilage and bone

UK scientists are working on new methods to regenerate cartilage and bone by delivering genes to stem cells within the body to instruct them to turn into bone cells.

Extreme gene pin-pointed

One teenager likes to snowboard off a cliff. Another prefers to read a book and wouldn't think of trading places. Why these differences exist is a mystery, but for the first time researchers have identified a possible genetic explanation behind risk-seeking behavior.

Study reveals critical molecular events in the origin of fat cells

A new study reveals critical molecular events in the origin of fat cells. The findings are central to understanding chronic diseases, such as obesity and diabetes, as fat cells produce hormones critical for metabolic control, the researchers said.

Drug AMD-3100 may help cancer patients who need stem cell transplants

A new drug may help cancer patients mobilize the cells necessary to restore their blood-forming system after high-dose chemotherapy, according to results from a clinical trial at the Kimmel Cancer Center at Thomas Jefferson University Hospital in Philadelphia and at other centers across the nation.
