AUSTRALIA – breakthrough in stem cell research

Scientists have made a breakthrough in stem cell research which raises the prospect of regrowing damaged sections of a person’s liver, pancreas or even their brain.
Researchers at the University of NSW have found a way to improve the lifespan and competitiveness of stem cells, overcoming a problem which otherwise saw their regenerative powers fade in about an hour.

Adult stem cells were given a gene to make them resistant to chemotherapy, handing them an “advantage” when used to treat damaged tissue in conjunction with the cancer-fighting treatment.
University of NSW Professor Peter Gunning said as the chemotherapy cleaned out

Scientists create stem cells to help decipher diseases

Douglas A. Melton

Scientists have created stem cells from patients suffering from 10 incurable diseases, from Down syndrome to diabetes and Parkinson’s – immortal cells that might one day be turned into repair material for wasting muscles or damaged brains.
The Harvard University-led team has taken skin and bone marrow cells from diseased patients and re-programmed those cells to behave like cells from days-old embryos.

The feat allows scientists for the first time to watch muscular dystrophy and other diseases unfold in a petri dish, “that is, to watch what goes right or wrong,” said Doug Melton, co-director of the Harvard

Stem cell jab ‘may boost muscle’

Muscle wasting linked to old age might one day be treated using stem cells, claim US scientists.

A University of Colorado team transplanted cells into mice and saw the muscle more than double in size – staying that way even into old age.

They say their work, reported in Science Translational Medicine, may have promise in treating muscle-wasting conditions such as muscular dystrophy.
A UK expert said producing a human treatment might be difficult.
Stem cells are cells found in the body which can divide and become a variety of different types of tissue.

Scientists believe they could potentially help treat a large number

Scientists discover new way to enhance stem cells to stimulate muscle regeneration

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy.

The research, to be published in the June 5 issue of Cell Stem Cell, shows for the first time that a protein called Wnt7a increases the number of stem cells in muscle tissue, leading to accelerated growth and repair of skeletal muscle.

“This discovery shows us that by targeting stem cells to boost their numbers, we can improve the body’s ability to repair

Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle

Image via Wikipedia

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers—including 2007 Nobel Prize winner Mario R. Capecchi—have created a “switch” that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. For humans, this work could lead to a genetic switch, or drug, that allows people to grow new muscle cells to replace those that are damaged, worn out, or not working for other reasons (e.g., muscular dystrophy). In addition, this same discovery also gives researchers
