Stem cell breakthrough: Scientists discover way to ‘grow your own’

Posted February 10, 2014

One of the most ethically sensitive issues in American society, save abortion, has been the issue of stem cells and, in particular, the harvesting of them from human embryos, a process which results in the embryo’s destruction. Now, however, scientists believe that they have discovered a “game-changer” in stem cell research: a way for humans to reproduce their own, bypassing the ethical problems associated with their harvesting in the past.

Using stem cells from hip replacements to help treat ageing adults

Posted January 30, 2014

The tissue normally discarded during routine hip replacements could be a rich new source of adult stem cells for use in regenerative medicine, UNSW-led research has found. With tens of thousands of hip replacement surgeries performed each year, this tissue could have “profound implications” in clinical use, the scientists say.

Stem cells injected into nerve guide tubes repair injured peripheral nerve

Posted January 10, 2014

Using skin-derived stem cells (SDSCs) and a previously developed collagen tube designed to successfully bridge gaps in injured nerves in rat models, the research team in Milan, Italy that established and tested the procedure has successfully rescued peripheral nerves in the upper arms of a patient suffering peripheral nerve damage who would have otherwise had to undergo amputations.

Stem cell research uncovers importance of cell cycle

Posted December 17, 2013

One of the biggest problems in stem cell research may not be a problem at all. Scientists have worried for years that stem cells grown in their labs were made up of many different kinds of cells, making them useless for stem cell therapies, but new research from the University of Georgia suggests they’re not different cells, some are just more mature than others.

The heart’s own stem cells play their part in regeneration

Posted November 30, 2013

Up until a few years ago, the common school of thought held that the mammalian heart had very little regenerative capacity. However, scientists now know that heart muscle cells constantly regenerate, albeit at a very low rate. Researchers at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, have identified a stem cell population responsible for this regeneration. Hopes are growing that it will be possible in future to stimulate the self-healing powers of patients with diseases and disorders of the heart muscle, and thus develop new potential treatments.

Beneficial effects of AFA on adult stem cells make it the anti-aging algae

Posted November 25, 2013

Studies have revealed that the consumption of Aphanizomenon flos-aquae (AFA) has beneficial effects on adult stem cells. That’s great news for those concerned about the effects of aging, because stem cells are incredibly important to our health, playing a major role in the ability of the body to age well.

New muscle power from the lab

Posted August 19, 2013

Unlike the heart muscle, the musculature of the locomotive organs has the capacity to heal itself. What makes this possible are muscle-specific stem cells known as satellite cells. Located on the muscle fibres, these cells can multiply when necessary and replace damaged muscle cells. Scientists from the Max Planck Institute for Heart and Lung Research recently succeeded in elucidating the role of an important factor in the regulation of self-healing.

Ginkgo biloba may boost brain functions by increasing stem cell growth: Rat study

Posted July 27, 2013

Supplementation with an extract from Ginkgo biloba may help to battle memory loss and cognitive impairments associated with dementia by encouraging the growth and development of neural stem cells, according new research in rats.

Melatonin pre-treatment is a factor that impacts stem cell survival after transplantation

Posted July 23, 2013

When melatonin, a hormone secreted by the pineal gland, was used as a pre-treatment for mesenchymal stem cells (MSCs) prior to their transplantation into the brains of laboratory animals to repair damage from stroke, researchers in China found that the stem cells survived longer after transplantation. Previous studies had shown that 80 percent of transplanted MSCs died within 72 hours of transplantation. By contrast, the melatonin pre-treatment “greatly increased” cell survival, said the researchers.

Injecting iron supplement lets scientists track transplanted stem cells

Posted July 12, 2013

A new, noninvasive technique for tracking stem cells after transplantation—developed by a cross-disciplinary team of radiologists, chemists, statisticians and materials scientists at the Stanford University School of Medicine—could help surgeons determine whether a procedure to repair injured or worn-out knees is successful.
