Research in Italy, in the coming years, will suffer much more compared to research in other countries, because, explained a study on the future of biomedical research in Italy described yesterday in Siena by Stefano Palumbo, “the national debate on bioethical issues will continue to be affected by pre-established ideological positions, and often, will be aimed at imposing limits on scientific research”.
Due to the overwhelming “majority of Catholic members in the National Bioethics Committee, Italy will be,” according to the study, “the most conservative country in the world regarding stem cells,” which will result in
StemCells Inc. announced preclinical data demonstrating that its proprietary human neural stem cells restored memory and enhanced synaptic function in two animal models relevant to Alzheimer’s disease (AD). The data was presented today at the Alzheimer’s Association International Conference 2012 in Vancouver, Canada.
The study results showed that transplanting the cells into a specific region of the brain, the hippocampus, statistically increased memory in two different animal models. The hippocampus is critically important to the control of memory and is severely impacted by the pathology of AD. Specifically, hippocampal synaptic density is reduced in AD and correlates with memory loss.

UC Irvine scientists have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer’s disease, raising hopes of a potential treatment for the leading cause of elderly dementia that afflicts 5.3 million people in the U.S.
Mice genetically engineered to have Alzheimer’s performed markedly better on memory tests a month after mouse neural stem cells were injected into their brains. The stem cells secreted a protein that created more neural connections, improving
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.
Led by researchers at the University of California, San Diego School of Medicine, scientists have, for the first time, created stem cell-derived, in vitro models of sporadic and hereditary Alzheimer’s disease, using induced pluripotent stem cells from patients with the much-dreaded neurodegenerative disorder.
“Creating highly purified and functional human Alzheimer’s neurons in a dish – this has never been done before,” said senior study author Lawrence Goldstein, PhD, professor in the Department of Cellular and Molecular Medicine, Howard Hughes Medical Institute Investigator and director of the UC San Diego Stem Cell Program. “It’s a first step. These aren’t perfect models.
