CXCL12 and neoplasm: Indeed, BC_038 and OVCAR-5 tumors had higher expression levels of the migratory chemokines CXCL10, CXCL12, and CCL19 (Figure 6) compared to SK-OV-3 and also shared a rather similar cytokine/chemokine profile (Supplementary Figure 7B) and immune cell composition, despite their different origin as PDX and established cancer cell line from a different tumor entity.
