Patent number: 8722401Abstract: A method for the in vitro production of a cell population P? from a cell population P, the production requiring the presence of at least one factor which is expressed by feeder cells, wherein a) feeder cells proliferate at a temperature T1, b) proliferated feeder cells are contacted with the cell population P, c) the cell mixture obtained at step (b) is cultivated at a temperature T2 which is chosen such that the cell population P proliferates and the feeder cells do not proliferate, the at least one factor being expressed by the feeder cells, and d) the cell population P? so produced is recovered.

Patent number: 7977093Abstract: An in vitro method for the obtention of a food- or auto-antigen specific Tr1 cell population from a leukocyte or a PBMC population, includes stimulating the PBMC or leukocyte population with the food- or auto-antigen, and recovering the food- or auto-antigen specific Tr1 cell population from the stimulated cell population. Preferably, the PBMC or leukocyte population is re-stimulated at least once with the same antigen after step (1), in the presence of IL-2 and at least one interleukin selected from the group consisting of IL-4 and IL-13. The in vitro method may further include a third step of expanding the recovered antigen-specific Tr1 cell population, advantageously by contacting them with feeder cells capable of expressing factors necessary for the expansion. Preferably, the feeder cells are recombinant insect feeder cells.Type: GrantFiled: July 3, 2006Date of Patent: July 12, 2011Assignees: INSERM (Institut National de la Sante et de la Recherche Medicale), TXCELLInventors: Hervé Groux, Françoise Cottrez, Arnaud Foussat, Valerie Brun
