...will get so used to accepting every inanity uttered near us that we will completely lose our critical faculties ... The word why is a wonderful dumb-conversation stopper." Your next brilliant brainchild may not survive Sindell's 11 steps to become viable, let alone profitable, but if his method truly does lead to fewer dumb conversations, let's hope it catches...
Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease...
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 to file a request for the first human trial using its cells sometime next year...
...create iPS cells without using viruses and genes. But Lanza and his team found a way around both: the researchers isolated the proteins made by the same genes Yamanaka used and "tagged" them with a message that allowed the proteins to slip easily into the cell. Yamanaka's method, on the other hand, relied on using viruses to ferry genes into the skin cell...
...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 could lead to a potential treatment to replace damaged eye cells in conditions such as retinitis pigmentosa or macular degeneration...
