...took a few bold steps forward Wednesday. As Congress gets set to vote on legislation that would expand federal funding for the field to include studies on excess IVF embryos, researchers in the U.S. and Japan announced exciting advances in their ability to turn back the clock on older, adult cells and get them to generate embryonic stem cells. The findings could expand the ways that doctors and patients eventually generate customized stem cells for treatments...
...indeed possible to take a skin cell from an adult patient and tweak it to revert to an embryonic-type cell, that would mean that any patient needing a stem-cell-based treatment could, in theory, heal himself. Last year, Yamanaka was the first to announce success with this approach, by exposing the cells to four growth factors and nutrients. But the stem cells he generated were genetically abnormal and unstable. Building on the initial technique, Yamanaka's group, as well as those led by Rudolph Jaenisch at Whitehead and Konrad Hochedlinger at HSCI, showed that the process does indeed...
...other concern is perhaps more daunting-two of the four factors that can turn back the clock on adult cells so efficiently are known to cause cancer. One, in fact, was the first gene discovered to cause cancer in mice. "Figuring out how to reprogram cells without directly exposing the cell to the cancer-causing effects of these genes is a major area of scientific activity, and would have to occur before we could consider using similar factor in humans," says Eggan...
...Dark blue was for work, for dressing up like an adult and going into the office. Dark blue helped keep me in J.Crew clothing and reminded me of what I have to look forward to upon graduation. Dark blue also helped put things in perspective. My coworkers, their families, and their jobs reminded me that doing poorly on my midterm would probably mean very little to me in the long...
...Harvard was, for me, a validation of having “done well” in high school. Finally, I thought, I had something to my name that people in the “real world” could appreciate as an example of success. As a young adult searching for a sense of security, I cherished that feeling of accomplishment and did not want to let it go. And so I came to Harvard bent on “doing well” here too. I approached this college like any obstacle I had already faced?...
