SkinGun shoots burn victims with their own stem cells

Guns are often thought about for their destructive nature, but a new kind of gun is set to help heal rather than harm. Called the SkinGun, the device applies stem cells to the site of a burn in a novel way, helping increase both treatment and recovery time over standard methods. New tests show that it delivered a healing spray with 200 times more coverage than traditional methods.Read More

Stem cell treatment reawakens limbs in wheelchair-bound stroke victim

While new tools have emerged to help rehabilitation along, the road back to a healthy life after suffering a stroke can be a long and challenging one. In research that could one day significantly cut recovery times for victims of these debilitating brain injuries, scientists have injected modified stem cells into the brains of patients and brought about substantial improvements to motor function, with one even regaining control of her limbs and leaving her wheelchair behind.

Using stem cells to save rhinos from extinction

The northern white rhino is right on the brink of extinction, with only three of the species left on the planet. There's zero hope for the animals surviving naturally, but a team of scientists believes it might still be possible to bring the species back from the brink, with hopes of using stored genetic information to produce a new population.Read More

Creation of insulin-releasing cells in a dish offers hope of diabetes therapy

A molecular switch could hold the key to a personalized cell replacement therapy for diabetes. Both Type 1 and Type 2 diabetes are characterized by an inability to produce (or process) insulin, which is required to regulate blood sugar levels. This has been linked to malfunctioning or failing beta cells in the pancreas, but so far scientists have struggled to produce effective replacement cells in the lab. Now a team at Salk Institute believes the problem has been solved.Read More

Looking to love handles to treat diabetes

If a patient has Type 1 diabetes, then their ability to produce insulin is inhibited, usually by a loss of beta cells in the pancreas. Researchers have been looking at ways to replace the lost population of cells, but the process is difficult, often requiring the patient's immune system to be suppressed in order to be effective. Now, researchers at ETH Zurich have made a big breakthrough, successfully creating functional beta cells using stem cells extracted from the fatty tissue of a 50 year-old patient.Read More

Humans could get salamander-like tissue regeneration abilities in "a few years"

In what could prove to be a game changer in stem cell therapy, a team led by scientists at the University of New South Wales (UNSW) have discovered a way to reprogram bone and fat cells to become stem cells that can regenerate multiple tissue types. The technique has already proved successful in mice and could be just a few years away from being safely available for regenerating any damaged tissue in humans.Read More

Mouse gums turned into fully functioning skin

While growing biological components in the lab such as a thymus gland, sperm cells, eye tissue and cartilage are becoming more and more commonplace, thus far, creating fully functioning lab-grown skin has eluded scientists. Previous attempts have produced epithelial cells only, which comprise the outer layer of skin. Now, researchers at Japan's RIKEN Center for Developmental Biology have created skin tissue complete with sebaceous glands as well as hair follicles. They started with mouse gums.Read More

Neurodegenerative disorders may meet their match with 3D micro-scaffold

Injecting reprogrammed stem cells into the brain to tackle neurodegenerative diseases isn't a new idea, but a new technique might significantly improve the effectiveness of the treatment. A team of sceintists, led by researchers at Rutgers University, has developed and conducted successful animal tests of a three-dimensional polymer micro-scaffold that dramatically improves cell survival rates following transplantation.Read More

Osteoporosis in mice reversed with single injection of stem cells

Age-related osteoporosis, where the bone structure deteriorates and becomes more vulnerable to fracture, is said to affect more than 200 million people worldwide. Drugs are available to treat or delay the condition, but a cure has remained elusive. Much-needed help may now be on the way, however, with scientists discovering healthy bone structure can be restored in mice with a single injection of stem cells.Read More

New molecule has stem cells primed for harvesting within the hour

Securing a match for a bone marrow transplant to treat a cancer patient can be difficult enough, but it is not all smooth sailing from that point either. Preparing a donor's stem cells for harvesting involves a lot of time and injections of growth factor to boost stem cell populations ahead of the procedure. But Australian scientists have now unearthed a more direct route, discovering a new molecule that entices an adequate number of stem cells out into the blood stream to make for a much easier, swifter collection.Read More
