The Ethics of Human-Animal Stem Cell Research
Sep 17th, 2016 | By Dr. Jim EckmanIn early August 2016, the National Institutes of Health (NIH) announced that it was planning to lift its ban on funding some research that injects human stem cells into animal embryos. This rather remarkable decision involves growing human tissues or organs in animals to better understand human diseases and develop therapies to treat them. That scientists are placing human cells into animals is not new; this has been a common practice for years. What is new here is that such implantations involve human stem cells being placed in animals. Human stem cells are placed into developing animal embryos where they can become any type of cell?for organs, blood or bones. The larger goal of such a practice could be, for example, growing a human kidney in a pig for a transplant back into a human.
