Abstract
In all forms of diabetes, β cell mass or function is reduced and therefore the capacity of the pancreatic cells for regeneration or replenishment is a critical need. Diverse lines of research have shown the capacity of endocrine as well as acinar, ductal and centroacinar cells to generate new β cells. Several experimental approaches using injury models, pharmacological or genetic interventions, isolation and in vitro expansion of putative progenitors followed by transplantations or a combination thereof have suggested several pathways for β cell neogenesis or regeneration. The experimental results have also generated controversy related to the limitations and interpretation of the experimental approaches and ultimately their physiological relevance, particularly when considering differences between mouse, the primary animal model, and human. As a result, consensus is lacking regarding the relative importance of islet cell proliferation or progenitor differentiation and transdifferentiation of other pancreatic cell types in generating new β cells. In this review we summarize and evaluate recent experimental approaches and findings related to islet regeneration and address their relevance and potential clinical application in the fight against diabetes.

Abstract
Insulin-producing cells derived from in vitro differentiation of stem cells and non-stem cells by using different factors can spare the need for genetic manipulation and provide a cure for diabetes. In this context, pancreatic progenitors differentiating to β-like cells garner increasing attention as β-cell replacement source. This kind of cell therapy has the potential to cure diabetes, but is still on its way of being clinically useful. The primary restriction for in vitro production of mature and functional β-cells is developing a physiologically relevant in vitro culture system which can mimic in vivo pathways of islet development. In order to achieve this target, different approaches have been attempted for the differentiation of pancreatic stem/progenitor cells to β-like cells. Here, we will review some of the state-of-the-art protocols for the differentiation of pancreatic progenitors and differentiated pancreatic cells into β-like cells with a focus on pancreatic duct cells.

Abstract
Notch2, a surface marker in cell lines, is used to isolate, identify and localise pancreatic cancer stem-like cells and is a target for therapy of these cells. Sphere formation was induced in Panc-1 and Bxpc-3 pancreatic cancer cell lines, and Notch2(+) cells were separated from Bxpc-3 and Panc-1 cell lines by magnetic activated cell sorting (MACS). Expression of stem cell-related markers, OCT4, Nanog and PDX1, were measured by immunofluorescent (IF) staining. Expression of Notch2 was also determined immunohistochemically in pancreatic tissues. Notch2(+) cells were transplanted in subcutaneous of mice. AQP1 and AQP5 were also measured by IF in Bxpc-3 cells. The Notch signal pathway inhibitor, Compound E (CE), was used to treat Notch2(+) Bxpc-3 cells, and their vitalities were subsequently measured by the CCK-8 method. Positive expression of OCT4, Nanog and PDX1 was observed in Notch2(+) cells. Notch2(+) cells at centroacinar cell (CAC) and terminal ductal locations expressed AQP1 and AQP5. They were strongly tumourigenic in mice, and CE inhibited proliferation of Notch2(+) Bxpc-3 cells to some degree. OCT4 and Nanog can be used as markers of self-renewal in pancreatic cancer stem cells. Notch2(+) cells in human pancreatic cancer Bxpc-3 and Panc-1 cell lines had the properties of cancer stem cells. The results suggest that Notch2(+) pancreatic cancer stem-like cells had a close relationship with CAC.
