Popis: | Summary Pluripotent stem cells have been proposed as an unlimited source of pancreatic β cells for studying and treating diabetes. However, the long, multi-step differentiation protocols used to generate functional β cells inevitably exhibit considerable variability, particularly when applied to pluripotent cells from diverse genetic backgrounds. We have developed culture conditions that support long-term self-renewal of human multipotent pancreatic progenitors, which are developmentally more proximal to the specialized cells of the adult pancreas. These cultured pancreatic progenitor (cPP) cells express key pancreatic transcription factors, including PDX1 and SOX9, and exhibit transcriptomes closely related to their in vivo counterparts. Upon exposure to differentiation cues, cPP cells give rise to pancreatic endocrine, acinar, and ductal lineages, indicating multilineage potency. Furthermore, cPP cells generate insulin+ β-like cells in vitro and in vivo, suggesting that they offer a convenient alternative to pluripotent cells as a source of adult cell types for modeling pancreatic development and diabetes. Highlights • Culture on 3T3 cells enables long-term self-renewal of human pancreatic progenitors • Proliferation requires EGF, FGF10, retinoic acid, and inhibition of Notch and TGF-β • Cultured progenitors upregulate genes required for mitosis and telomere maintenance • Pancreatic duct and β-like cells are generated in vitro and in vivo In this article, Trott and colleagues describe conditions that enable long-term self-renewal of pancreatic progenitors derived from human pluripotent stem cells. These cultured pancreatic progenitors can be expanded for at least 20 passages and are capable of differentiation into multiple pancreatic lineages, including β-like cells, both in vitro and in vivo. |
