Researchers at the Joslin Diabetes Center have shown that insulin-producing pancreatic beta cells can form after birth or after injury from progenitor cells within the pancreas that were not beta cells, a finding that contradicts a widely-cited earlier study that had concluded this is not possible. The study, published online the week of November 24 in the Proceedings of the National Academy of Sciences Early Edition, identifies the source of the progenitor cells as being pancreatic duct cells.
