Patent number: 8927274Abstract: A method of generating pancreatic progenitor cells is disclosed. The method comprises: (a) differentiating stem cells under conditions such that at least a portion of the cells express glucose transporter 2 (GLUT2) so as to generate GLUT2-expressing cells; and (b) enriching for the GLUT2-expressing cells so as to generate a population of GLUT2 enriched cells, wherein at least 80% of the population of GLUT2 enriched cells express GLUT2, thereby generating pancreatic progenitor cells. Isolated populations of cells generated according to the method, pharmaceutical compositions comprising same and uses thereof are also disclosed.Type: GrantFiled: April 12, 2011Date of Patent: January 6, 2015Assignee: Technion Research & Development Foundation LimitedInventors: Joseph Itskovitz-Eldor, Bettina Fishman, Hanna Segev

Publication number: 20150004612Abstract: A method of generating an induced progenitor population (iPP) of cells and/or induced population of cells from somatic cells, comprising the steps: a) obtaining a starting cell population, wherein cells of the starting cell population comprise, or are contacted with, a nucleic acid molecule encoding four reprogramming factors under the control of a control element, wherein the four reprogramming factors are optionally Oct4, Klf4, Sox2 and c-Myc, and wherein the control element prevents or stops expression of the reprogramming factors under its control in the absence of induction by an inducing agent; and b) transiently inducing expression of the reprogramming factors in the starting cell population to obtain an iPP, c) optionally isolating the iPP, and d) terminating the transient induction while the proliferative capacity of the iPP remains under the control of the one or more exogenous reprogramming factors to produce an induced population of cells.Type: ApplicationFiled: June 3, 2014Publication date: January 1, 2015Inventors: Thomas K. Waddell, Li Guo, Andras Nagy
