Restoration of damaged β-cells by transplantation from exogenous sources or by endocrine pancreas regeneration would be ideal therapeutic options. Stem cells of both embryonic and adult origin offer some interesting alternatives, taking into account the latest advances indicating that these cells could be the potential building blocks from which insulin secreting cells could be obtained in vitro under appropriate culture conditions. Although it has been reported that insulin-producing cells derived from stem cells have been shown to reverse experimentally induced diabetes in animal models, several concerns need to be solved before finding a definite medical application. These refer mainly to the obtainment of a cell population as similar as possible to pancreatic β-cells, and to the problems related with the immune compatibility and tumor formation. This review will describe the different approaches that have been used to obtain insulin-producing cells f
