Stem cells and stem cell therapyNews & ViewsThe two broad categories of mammalian stem cells are: embryonic stem cells, derived from blastocysts, and adult stem cells, which are found in adult tissues. In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells. Why do some scientists and politicians insist on exploiting embryos? Interview with C. Christopher Hook 2004-11-17 November 2004 48 11 74 C. Christopher Hook, director of ethics education for the Mayo Graduate School of Medicine, knows blood very well. As an experienced hematologist and a senior fellow at the Center for Bioethics and Human Dignity, he's done a lot of thinking about the debate over stem cells. Research on stem cell interaction with new biomaterial has yielded three (3) successful publications in international scientific journals by National University of Singapore and Nanoscience and Nanotechnology Initiative (NUSNNI) and StemLife Berhad. Support and funding from StemLife Berhad (StemLife), enabled the study of the interaction of novel nanofibers with bone-forming stem cells.  |
