5. Stem-Cell-Created Mice The birth of yet another laboratory mouse is hardly worth noting - unless the furry creature is the first to be developed from stem cells that do not involve embryonic cells. That deserves to be called a breakthrough. The new pups, whose creation in two separate...
Still, the rapid pace of the research means we may not have to wait long. "We really lucked out," says Lanza. "These iPS cells were just discovered a few years ago, and here we are three years later with a method safe enough to actually use in people." ACT plans...
So far, the ACT group says the iPS cells generated using their method are equivalent to those made using Yamanaka's strategy. In fact, they seem to flourish more robustly than the traditional iPS cells, at least in lab tests that involve regrowing certain cells found in the retina. This...
Dr. Arnold Kriegstein, director of the Institute for Regeneration Medicine at the University of California, San Francisco, is excited by the advance but notes that it is still relatively inefficient. "The ability to make cell lines from patients with any risk of genetic alteration is a significant step, but the...
While the new iPS cells may be safer, even Lanza admits there is much that researchers still need to learn about how they will react once inside a patient's body. The most pressing question remains whether iPS cells - or the nerves, muscles or any of the 200 other types...
