Process for preserving insulin secreting cells intended to be transplanted, including the following steps: introducing an initial volume of culture medium and insulin-secreting cells into a culture container, providing a culture medium source, and replacing, at time intervals below 8 hours, the culture medium in the culture container with culture medium from the source so as to renew the culture medium contained in the container.

Process for preserving insulin-secreting cells intended to be transplanted in a patient

The present invention relates to a process for obtaining mammalian insulin secreting cells in vitro, characterized in that it contains the following steps: a) preparation of the mammalian pancreatic tissues by removal of a pancreas, b) dissociation of the pancreatic tissues obtained in step (a) into isolated pancreatic cells, c) possibly the elimination of the endocrine cells from the pancreatic cells isolated in step (b), d) induction of dedifferentiation of the cells isolated in step (b) into ductal precursor cells, e) induction of redifferentiation of the ductal precursor cells obtained in step (d) into insulin secreting cells. It also concerns the use of the insulin secreting cells thus obtained for the preparation of a pharmaceutical composition which can be used for the treatment of pancreatic pathologies and particularly diabetes.
