But Brent Reynolds and Sam Weiss at Neurospheres, a Canadian biotechnology company, have shown that they are still alive and well in adults, and that they can be prompted to recreate lost cellpopulations.
Similarly, Mary Helen Barcellos-Hoff, a professor of radiation oncology and cell biology at NYU and her team lost mouse populations involved in studies of how radiation exposure increases cancer risk as well as how radiation can be targeted to treat tumors.
