...Cell Stem Cell, represent true milestones, not only in the field of stem-cell research, but in the broader discipline of early biological development. Led by Shinya Yamanaka at Kyoto University, one group successfully coaxed a mouse skin cell to reverse its development and return to an embryonic stage at which it produced stem cells. Two other groups, based at Harvard Stem Cell Institute (HSCI) and the Whitehead Institute for Biomedical Research at MIT, obtained similar results working independently. In the final paper, Kevin Eggan, also at HSCI, showed that even fertilized mouse zygotes at the one-cell stage...
...meantime, Eggan's group has provided an alternative method for generating customized stem cells that would take advantage of the early-stage embryos frozen in IVF centers around the country. The most reliable way of generating patient-specific stem cells remains nuclear transfer-taking the nucleus from a patient's skin cell and inserting it into an egg that has had its nucleus removed. This hybrid then begins to divide, and within a few days, generates stem cells that are genetically identical to the patient. The problem, however, as Eggan puts it, is that "there are never any extra unfertilized...
Nine hundred bright-eyed Harvard Business School (HBS) graduates of the Class of 2007 blanketed the lawn in front of Baker Library yesterday as American Express Company Chairman and CEO Kenneth I.

...Fortune 500 companies in 2004. He has gone from being a “pathfinder,” as Ebony called him, to a staple of the financial world, responsible for the rejuvenation of one of the world’s top financial firms. He will take the stage this afternoon at Harvard Business School (HBS) to address graduates of the Class of 2007, parents, and alumni as part of the Class Day ceremony. Chenault is president of AMEX and has chaired the board of directors since 2001. He is credited with reorienting AMEX’s financial focus, increasing...
