...celled zygotes, or fertilized embryos that are on the verge of making their first cell division, can act just like the emptied-out egg in the nuclear transfer process. And because more of these zygotes are available than eggs, it may give patients another way of obtaining customized stem cells. In fact, notes Eggan, there may be even more such zygotes available if you count the abnormally fertilized embryos that IVF clinicians discard immediately. Anywhere from 3% to 10% of IVF embryos get either too many or too few chromosomes when they are fertilized; these embryos have no chance...
...that's what has stem cell researchers excited again. While these findings do not address perhaps the thorniest aspect of embryonic stem cell research-the controversy over the ethics of experimenting and manipulating embryos -they do highlight how little we know about stem cells and early development, and how powerful that knowledge can be, once we attain...
...result has been an institution dominated by individual fiefdoms and parochial interests and that is averse to interdisciplinary endeavor. Faust must break down these entrenched barriers—a move that will likely anger many. Luckily, Faust has a solid model to build on with the nascent Harvard Stem Cell institute and the recent creation of the first inter-faculty department.Faust must also deal with a recalcitrant and old-fashioned Faculty of Arts and Sciences. To say that the Faculty is currently in a difficult position would be an understatement—it faces a budget deficit and must implement...
...Bioengineering Debra T. Auguste was not directly involved with the creation of the new Life Sciences curriculum at Harvard, she is in many ways a living example of breakthroughs that can be gained from multidisciplinary research. Auguste’s research focuses on better understanding the biology of stem cells and interfacing this knowledge with tissue engineering to improve drug delivery and to better understand diseases...
...Auguste creates micro-environments in her lab that simulate bodily conditions in an attempt to better grasp the way that diseases such as cancer and diabetes affect human cells and tissue. Her work is focused on two specific areas—drug delivery and stem cell differentiation...
