In addition, concerns have been raised about the consent process for the derivation of some of these NIH-approved lines (7). Canadian Aboriginal Death Rituals, Embryonic stem cells can be readily grown in culture and exhibit unique properties, including spontaneous differentiation into three germ layers in vitro or teratoma formation in vivo. Somatic cells can be reprogrammed to form pluripotent stem cells (45, 46), called induced pluripotential stem cells (iPS cells). Eliza Gilkyson, Researchers need to communicate the distinction between the long-term hope for effective treatments and the uncertainty inherent in any phase I trial. Native American History For Kids,
Clark JW , It would be unfortunate if iPS cell lines that turned out to be extremely useful scientifically (for example because of robust growth in tissue culture) could not be used in additional research because the somatic cell donor objected.
