Alzheimer’s Neurons From Pluripotent Stem Cells

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.

China and California collaboration on Stem Cells

The California Institute for Regenerative Medicine (CIRM) and the Chinese Ministry of Science and Technology (MOST) have agreed to collaborate on stem cell research. The agreement will make it easier to form cross-border teams that are working in similar areas. If the teams’ funding requests are approved, the researchers in each country will be supported by their respective agency, CIRM or MOST. The formal announcement, made today, adds details to a story that ChinaBio® Today originally broke late last week (…)

“Our collaboration will benefit patients in our countries and patients around the globe,” said Wan Gang, Minister, MOST. “We

Drs. Scott Kitchen, Zoran Galic, Jerry Zack of the UCLA Broad Stem Cell Research Center and AIDS Institute and their colleagues demonstrated for the first time that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells. The process could potentially be used against a range of chronic viral diseases.

The study, published Dec. 7 in the-peer reviewed online journal PLoS ONE, provides proof-of-principle, a demonstration of feasibility, that human stem cells can be engineered into the equivalent of a genetic vaccine.

“We have demonstrated in this proof-of-principle study that

New stem cell therapy could be used to halt Huntington’s advance

A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington’s disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death. The findings, now available online in the journal Molecular and Cellular Neuroscience, suggest a promising approach that might block the disease from advancing.

“For the first time, we have been able to successfully deliver inhibitory RNA sequences from stem cells directly into neurons, significantly decreasing the synthesis of the abnormal huntingtin protein,” said Jan A.

Scientists measure communication between stem cell-derived motor neurons, muscle cells

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure communication between stem cell–derived motor neurons and muscle cells in a Petri dish.

The study provides an important proof of principle that functional motor circuits can be created outside the body using these neurons and cells and that the level of communication, or synaptic activity, between them can be accurately measured by stimulating the motor neurons with an electrode and then tracking the transfer of electrical activity into the muscle cells
