Pan02 murine pancreatic tumours from the orthotopic pancreatic tail tumour model treated with saline (control; CT), FRAX597 (FRAX), gemcitabine (Gem), or FRAX597 and gemcitabine (Gemâ+âFRAX) at the doses given in the Materials and Methods section, were fixed and stained for the proliferative marker, Ki67.
