In the version of this article initially published in print and online there was a mistake saying small-molecule agents were used in preclinical studies. The sentence should have read “preclinical studies have shown that a few adenovirus-delivered transcription factors could induce exocrine pancreatic cells to transdifferentiate into insulin-producing cells.39” The error has been corrected for the HTML and PDF versions of the article.
