Ghrelin-expressing cells are rare in the adult pancreas; however cells that formerly expressed ghrelin or their progeny contribute to the final set of endocrine cells in the islet, specifically within the alpha and PP cells. Interestingly, not all α and PP cells are descendants of ghrelin-expressing cells, suggesting that two distinct populations of glucagon- and PP-expressing cells inhabit the adult pancreas. Moreover, we identified Neurog3-independent ghrelin-expressing cells that have the potential to contribute to exocrine and ductal tissue.
