Researchers directly turn mouse skin cells into neurons

Even Superman needed to retire to a phone booth for a quick change. But now scientists at the Stanford University School of Medicine have succeeded in the ultimate switch: transforming mouse skin cells in a laboratory dish directly into functional nerve cells with the application of just three genes. The cells make the change without first becoming a pluripotent type of stem cell — a step long thought to be required for cells to acquire new identities.

The finding could revolutionize the future of human stem cell therapy and recast our understanding of how cells choose and maintain their specialties

Policies aimed at curtailing embyronic stem cell research would also hurt iPS cell research, expert finds

Any legislation that slows human embryonic stem cell research is likely to also seriously harm the study of induced pluripotent stem cells, according to a new study by researchers at the Stanford University School of Medicine, the Mayo Clinic and the University of Michigan.

The finding strongly refutes the idea that embryonic stem cell research can be abandoned in favor of the less-controversial iPS cells, which are derived from adult human tissue.

“If federal funding stops for human embryonic stem cell research, it would have a serious negative impact on iPS cell research,” said Stanford

Efficient process using microRNA converts human skin cells into neurons

The addition of two particular gene snippets to a skin cell’s usual genetic material is enough to turn that cell into a fully functional neuron, report researchers from the Stanford University School of Medicine. The finding, published online July 13 in Nature, is one of just a few recent reports of ways to create human neurons in a lab dish.

The new capability to essentially grow neurons from scratch is a big step for neuroscience research, which has been stymied by the lack of human neurons for study. Unlike skin cells or blood cells, neurons are not something that’s easy
