A novel pancreatic tumour and stellate cell 3D co-culture spheroid model

Background Pancreatic ductal adenocarcinoma is a devastating disease with poor outcome, generally characterized by an excessive stroma component. The purpose of this study was to develop a simple and reproducible in vitro 3D-assay employing the main constituents of pancreatic ductal adenocarcinoma, namely pancreatic stellate and cancer cells. Method A spheroid assay, directly co-culturing human pancreatic stellate cells with human pancreatic...
