To identify the paracrine factors predominantly secreted by pericytes (PCs) derived from EGFR‐mutated NSCLC patient tumors, we conducted a comparative secretomics analysis of conditioned medium (CM) from PCs derived from three different EGFR‐mutated patients and the EGFR‐mutated NSCLC cancer cell line HCC827. Here, EGFR is linked to non-small cell lung carcinoma.
