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
Researchers for the first time have been able to demonstrate fully functional complex tissues of human organs i.e. intestines, obtained using stem cell technology, which finds applications in laboratory research as well as medical purposes. The paper was published in the journal Nature.
“This is the first study to demonstrate that human pluripotent stem cells in a petri dish can be instructed to efficiently form human tissue with three-dimensional architecture and cellular composition remarkably similar to intestinal tissue,” said Dr. James Wells, a leading researcher at the Medical Center’s Children’s Hospital of Cincinnati. “The hope is that our ability
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
“Behind the embryonic stem cell war is just a war of patents,” led an article in the Osservatore Romano newspaper by Angelo Vescovi, a geneticist at the Niguarda Hospital in Milan and a professor at the Università Bicocca, who has always been against embryonic stem cell research and supporter of ‘law 40’ (recently declared unconstitutional by authorities).
“The production of embryonic stem cells by reprogramming adult cells discovered recently is not only better than methods that use human embryos, but is also based on new techniques, which are not protected by patents that currently govern the use of stem cells
American Doctors and Patients Challenge the FDA to Save Lives Rather Than Allow Patients to Needlessly Die
A couple of weeks ago, the American Stem Cell Therapy Association (ASCTA) was formed by a group of doctors, not to debate the pros and cons of embryonic stem cell research and adult stem cell research, but to […]
