VEGFA and cancer: Using a cell co-culture system, we found that VEGFA-EGFP signal was detected both in cancer cells (4T1-HLC cells) and in macrophages (RAW264.7) upon TG-VHS treatment, which supports our proposed working model (Figure 3C) in which VEGFA co-phagocytosis upon TG-VHS treatment occurs via a 2-step process.
