Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington’s disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models.
Induced pluripotent stem cells (iPSCs) can be genetically engineered from human somatic cells such as skin, and can be used to model numerous human diseases. They may also serve as sources of transplantable cells that can be used in novel cell therapies. In the latter case, the patient provides a sample of his or her own skin to the laboratory.

Summit at Lake Como with 100 European stem cell experts.
At the summit, 16 research teams part of the Neurostemcell consortium that have been working for months on finding treatments for Parkinson’s and Huntington’s disease met. The network, coordinated by Elena Cattaneo, Director of Unistem, the interdepartmental stem cell research centre of the University of Milan, met on April 1 in Bellagio, on the shores of Lake Como for their first annual meeting.
“The meeting is an opportunity to discuss the results obtained until now and to refine our methods,” explained Cattaneo, who pointed out the objective of
Scientists at the UCSF-affiliated Gladstone Institutes and an international team of researchers have generated a human model of Huntington’s disease — directly from the skin cells of patients with the disease.
For years, scientists have studied Huntington’s disease primarily in post-mortem brain tissue or laboratory animals modified to mimic the disease. Today, in Cell Stem Cell, the international team shows how they developed a human model of Huntington’s disease, which causes a diverse range of neurological impairments. The new model should help scientists better understand the development of Huntington’s — and provide better ways to identify and screen potential therapeutics

An experiment successfully performed by researchers at the University of Wisconsin-Madison and the University of Missouri in Colombia, described in Nature magazine shows that cells removed from a patient’s skin and transformed into cells similar to embryonic stem cells have become a laboratory model for diseases and can be observed in real time and studied to find new cures. The researchers recreated spinal muscular atrophy (SMA) pluripotent stem cells removed from the skin of a child affected by the neurodegenerative genetic disease. In the laboratory, the cells behaved exactly as they do in

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
