In the original article, there was an error in the Acknowledgments. It was written that Professor Toshihiko Ezashi and Professor R. Michael Roberts provided “three human pluripotent stem cells”; however, this is not accurate. They provided “genomic materials obtained from three human pluripotent stem cells.”
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
