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.

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.

Australian discovery of adult stem cells in the uterus

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.

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.

New roles for granulocyte colony-stimulating factor (G-CSF) in treating stroke

In a study appearing online on July 7 in advance of print publication of the August 1 issue of the Journal of Clinical Investigation, Armin Schneider and colleagues from Axaron Biosciences describe new roles for granulocyte colony-stimulating factor (G-CSF) in treating stroke and other central nervous system roles of this protein.

Researchers clarifiy role of Notch protein in T-cell development

Researchers at the University of Pennsylvania School of Medicine have recently clarified the role of the Notch protein in T-cell development. T cells are required for many aspects of immunity, including fighting viral infections, providing cancer surveillance, and regulating multiple aspects of the immune response.

Discovery of genes that impact the development and function of blood stem cells

Researchers at the University of Minnesota have identified for the first time a group of genes that impact the development and function of blood stem cells, a discovery that brings researchers a step closer to harnessing the power of stem cells for disease treatments.

Functional analysis of human hematopoietic stem cell gene expression using zebrafish

What do you get when you mix RNA chips and zebrafish? A new two-stage method for studying human gene expression differs in human stem cells and progenitor cells, according to a new article in the open access journal PLoS Biology.

Scientists discover identifying markers for primitive blood-forming stem cells - simplifies cell identification

Scientists at the University of Michigan Medical School have discovered the biological equivalent of a grocery store bar code on the surface of primitive, blood-forming stem cells in mice. Called hematopoietic stem cells, they give rise to all the different types of specialized cells found in blood.

Adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply

In a ground-breaking study, scientists at Children's Hospital of Pittsburgh have discovered that adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply, a previously unknown characteristic indicating that post-natal stem cells may play an important therapeutic role.
