Abstract
The present invention relates to a cryopreserved in vitro cell culture comprising human pancreatic progenitor cells that co-express pancreatic-duodenal homeobox factor-1 (PDX1) and NK6 homeobox 1 (NKX6.1) and are chromogranin negative. The present invention also relates to a method for cryopreserving an in vitro population of human pancreatic progenitor cells that co-express PDX1 and NKX6.1 and are chromogranin negative.
