Figure 6: Genetic modification of human ductal cell line HPDE induces invasive PDA development.

(a) Genomic DNA PCR for assessing the presence of lentiviral transgenes in HPDE cells. (b) Relative mRNA expression level of oncogenic KRAS and ERBB2 transgene. Error bars=s.d.; n=2. (c) Indel efficiency of each indicated genomic locus assessed by TIDE analysis. (d) Stereoscopic and representative haematoxylin and eosin (H&E) and anti-CK19 (green) immunostaining images of the tumours formed in the transplanted pancreas with HPDEKECST. Red arrows indicate tumour nodules. (e) Representative H&E staining of lung with metastatic cells found in ID 211. The metastatic cells are CK19+ (green, bottom). (f) Stereoscopic and representative H&E staining images of the tumours formed in the transplanted pancreas with HPDEKCST. Scale bars, 200 μm.
