Initial characterization of fetal pancreatic cells. (a) and (b) show morphology of cells in culture after 2 d and 7 d. Note epithelial morphology of EpCAM-positive cells. (c) shows RT-PCR for genes as indicated. Lanes 1 to 6 show results from mature human pancreatic islets, intact fetal pancreas, cells after early term culture (1 to 2 d) or longer culture (10 to 14 d). For comparisons, β-actin and glyceraldehyde phosphate dehydrogenase (GAPDH) genes were included.
