Vitamin C Enhances the Generation of Mouse and Human Induced Pluripotent Stem Cells

Image via Wikipedia

Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by defined factors. However, the low efficiency and slow kinetics of the reprogramming process have hampered progress with this technology. Here we report that a natural compound, vitamin C (Vc), enhances iPSC generation from both mouse and human somatic cells. Vc acts at least in part by alleviating cell senescence, a recently identified roadblock for reprogramming.

In addition, Vc accelerates gene expression changes and promotes the transition of pre-iPSC colonies to a fully reprogrammed state. Our results therefore highlight a straightforward method for improving the speed and

Induced neural stem cells: Not quite ready for prime time

The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy.

However, a new study published this week (Feb. 15) in the Proceedings of the National Academy of Sciences comparing the ability of induced cells and embryonic cells to morph into the cells of the brain has found that induced cells — even those free of the genetic factors used to program their all-purpose qualities — differentiate less efficiently and faithfully than their embryonic counterparts.

The finding that induced cells are

Israeli researchers discover method to neutralize tumor growth in embryonic stem cell therapy

Hebrew University of Jerusalem

Researchers at the Hebrew University of Jerusalem discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells, said the university on Wednesday.
The researchers’ work paves the way for further progress in the promising field of stem cell therapy, said the press release of the university sent to Xinhua.

According to the release, human embryonic stem cells are theoretically capable of differentiation to all cells of the mature human body (and are hence defined as “pluripotent“).
This ability, along with the ability to remain undifferentiated indefinitely in culture, make regenerative medicine using human

Al Gore on board for $20M stem cell venture

Al Gore (via last.fm)

Former Vice President Al Gore Endorses Trans-Pacific Collaboration to Promote Use of Patient Cells for Drug Discovery and Development and Cell-Based Therapies iZumi Bio, Inc., and Kyoto University‘s Center for iPS Cell Research and Application (CiRA), today announced a collaboration to promote the basic research, development and application of induced pluripotent stem (iPS) cell technology – a form of cellular reprogramming which originated in Japan – with the goal of advancing drug discovery and enabling cell-based therapies.

“Stem cell research holds great promise for the creation of new therapies that could revolutionize the treatment of disorders such

Veterinarian uses stem cells to heal spinal cord illness

With veterinarians across the country training to use stem cells for tendon and ligament repair, a professor at the University of California, Davis (UC Davis) wants to take the technology a step further by applying them to chronic, cell-based diseases.

Richard Vulliet, DVM, is very early into the work. But he is optimistic about the evidence as it exists, of course, and he may have had a success.

Vulliet has treated four dogs with degenerative myelopathy with their own stem cells, which he prefers to call mesenchymal stem cells or pluripotent marrow stromal cells. The terminology has evolved and those names
