Some Human Stem Cells Used In Research Laboratories May Have Cancer-Causing Mutations, Study Suggests.

reports some human stem cells that have been grown in laboratories for research on experimental treatments “contain serious cancer-causing mutations,” according to a study published online in Nature. Researchers analyzed “samples of most of the human embryonic stem cell lines registered with the National Institutes of Health for use in both basic research and in developing therapies for patients,” and “found that five of the 140 lines had cells with a cancer-causing mutation.” The article mentions that the “Food and Drug Administration does not require researchers to sequence the DNA of cells before putting them into people.” https://www.statnews.com/2017/04/26/stem-cells-cancer-mutations/
