Immune landscape of PDAC. A Representative images of mIHC in PDAC and adjacent noncancerous TMA cores, which were exported from Qupath software. Cell markers, including PanCK, CD68, PD1, PD-L1, and CD8 were labeled with different colors. B Representative images of quantitative pathological analysis. Tumor and stromal regions were separated according to PanCK expression. The PD1 + /CD8 + cells were identified by single measurement classifier, while CD68 + /PD-L1 + cells were identified by training the object or pixel classifier
