Pluripotent stem cells are those capable of differentiating into any type of tissue, hence the attractiveness of embryonic stem cells, or hESCs, also called ES cells, which are also pluripotent. "As a result, induced pluripotent stem cells do not offer an easy solution to the difficult ethical questions surrounding embryonic stem cell research," he says. He notes the science behind adult tissue that can be "reprogrammed," to produce human induced pluripotent stem cells is still in its infancy, having become widely available in 2007. "The incentives to use both types of cell in comparative studies are high," says Jason Owen-Smith, a sociologist at University of Michigan. The research appears in the June 9 journal Cell. "It is particularly interesting because it uses new analytical techniques to advance our understanding of how the implementation of policy in one area can affect scientific research in another area." "This is an important study that systematically examines the coauthorship networks of stem cell research articles and uses those to understand the interactions between two complementary areas of research," says Julia Lane, program director for Science of Science & Innovation Policy at the National Science Foundation, which funded the study. Instead, the two cell types have proven to be complementary and any disruption of federal funding, they say, would negatively impact stem cell research overall. The researchers analyzed more than 2,000 scientific papers and found reprogrammed adult cells are not replacing human embryonic stems cells in the laboratory. recently investigated whether the increased number of studies with induced pluripotent stem (iPS) cells-adult cells that have been coaxed into an "embryo-like" state-has changed the overall course of research in the field. Researchers from the University of Michigan, Stanford University and the Mayo Clinic in Rochester, Minn. New research says studying both reprogrammed adult cells and embryonic stem cells can benefit medical science, but banning the study of embryonic stem cell research could harm studies of reprogrammed adult cells.
