After much hope and controversy, for the first time stem cells have proven to have the ability to cure blindness.
The news comes from a study on age-related macular degeneration (AMD) of the retina, the most common cause of blindness in individuals over the age of 50.
The Sunday Times reports that the treatment was developed by a group of British researchers, who say that in the next six to seven years the treatment will become a routine operation, which will not last more than an hour.
The treatment involves the replacement of a layer of degenerated cells with new cells created
Progress has been made against strokes thanks to stem cells. British researchers, thanks to these cells, have managed to repair brain tissue damaged by a stroke. The study, financed by the research council on biological and biotechnological sciences of the United Kingdom, was published in Nature Biomaterials. The team from the Institute of Psychiatry at the University of Nottingham, used a biodegradable polymer called Plga to build a scaffold for neural cells.
Using these they filled the cavity left by a stroke. This allows, explained Mike Modo, psychiatrist at King’s College in London and coordinator of
Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.
Collaborators from Harvard University, Massachusetts General Hospital (MGH), Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School (HMS) transplanted normally functioning embryonic neurons at a carefully selected stage of their development into the hypothalamus of mice unable to respond to leptin, a hormone that regulates metabolism and controls body weight. These mutant mice usually become morbidly obese, but the neuron transplants repaired defective brain circuits, enabling
A team of scientists has discovered what could be a novel source for researching and potentially treating Alzheimer’s disease and other conditions involving the destruction of brain cells.
Researchers at the University of California San Francisco-affiliated Gladstone Institutes converted skin cells from mice and humans into brain stem cells with the use of a protein called Sox2. Using only this protein to transform the skin cells into neuron stem cells is unusual. Normally, the conversion process is much more complex.
Stem Cell Research Doctor Helps Woman With Brain Injury
In another victory for stem cell research using Adult Stem Cells, a woman in India is recovering from a traumatic brain injury suffered in a car accident. Madhumalika, 27, had her own adult stem cells implanted into her brain for the therapy and treatment.
In a Coma, […]
