CALR and neoplasm: ICAM1, MPO and neuropilin-1 were localized in the proximal cell death and neutrophil-rich assay region, whereas PD-L1, galectin-3, MHC-I and calreticulin were localized mostly on tumor cells distal from the well, with the latter two decreasing in abundance with increasing distance from the reservoir (Fig. 5a and Extended Data Fig. 6a).
