Recent findings from the Laboratory of Neurobiology at Northeastern, led by biology professor and chair Günther Zupanc, and published online in the scientific journal Neuroscience, demonstrate the mechanism by which new neurons find their ultimate home — research that Zupanc hopes will offer insight into the regenerative potential of the human brain.
In 1989, scientists discovered that two areas of the human brain — the hippocampus and the olfactory bulb — are capable of generating neurons during adulthood. In the last decade, adult stem-cell research has shown that latent stem cells also exist in other regions.
In principle, this information could
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

Neurodegenerative conditions are, at this point, diseases that cannot be treated, and that progress until they finally claim the lives of their victims. They include such awful disorders as Parkinson’s, Alzheimer’s and Huntington’s, whose effects on the human brain can, at this point, only be postponed and alleviated, but not prevented or treated. Now, a new type of treatment, relying heavily on the power of stem cells, may offer a ray of hope to people suffering from these diseases.
In lab tests, researchers injected stem cells into the brain of animal models. The cells were harvested from the
Scientists in the US have made a major breakthrough that has the potential for people with brain damage, caused by epilepsy or Parkinson’s for example, to use their own brain stem cells as a treatment.
Steven Roper of the University of Florida discovered that stem cells from the human brain that were transplanted into the brains of newborn rats matured and were able to function just like native rat cells.
The researchers found that the adult stem cells had the ability to turn into all types of brain tissue in the rats, including the neocortex, which deals with higher processing, and

Scientists have created a way to isolate neural stem cells – cells that give rise to all the cell types of the brain – from human brain tissue with unprecedented precision, an important step toward developing new treatments for conditions of the nervous system, like Parkinson’s and Huntington’s diseases and spinal cord injury.
The work by a team of neuroscientists at the University of Rochester Medical Center was published in the Nov. 3 issue of the Journal of Neuroscience. Neurologist Steven Goldman, M.D., Ph.D., chair of the Department of Neurology, led the
