Expansion of adult human pancreatic tissue yields organoids harbouring progenitor cells with endocrine differentiation potential

Gene expression profiles from ALDH high cells sorted from expanded adult human pancreatic organoids are more similar to fetal pancreatic tissue and ALDH high cells sorted from expanded fetal human pancreatic organoids than to adult human islets or adult islet-depleted exocrine tissue. RNA was isolated from ALDHhi cells sorted from organoids after 7 days expansion derived from human adult pancreatic tissue, ALDHhi cells sorted from organoids after 7 days expansion derived from human fetal pancreatic tissue, primary fetal pancreatic tissue, adult human islets from different donors and adult exocrine (islet-depleted) pancreatic tissue from different donors.
