VEGFA and neoplasm: VEGF-A is secreted not only by endothelial cells [25–28], but also by other cells, in response to hypoxia, i.e., in tumor cells [25, 29], macrophages [25, 27, 28], platelets [28], keratinocytes [25, 28], kidney mesangial cells [25, 28], activated T-cells [25, 27, 28], leukocytes [26], dendritic cells [30], retinal pigmentary epithelial cells [31], Müller cells in the retina [32], astrocytes [25], osteoblasts [25], bronchial and alveolar epithelial cells [33], pericytes [34] and vascular smooth muscle cells (VSMCs) [35].
