VEGFA and non-small cell lung carcinoma: showed that M2 TAM significantly enhanced the expression levels of VEGF-A and VEGF-C of NSCLC cells, whereas M1 TAM only upregulated the expression levels of VEGF-A in NSCLC cells, indicating that TAMs are significantly associated with vascular and lymph angiogenesis, which in turn promotes the progression of NSCLC 5.
