VEGFA and acute kidney injury: Although the molecular mechanism responsible for capillary rarefaction has not been elucidated [21], decreased expression of vascular endothelial growth factor (VEGF), an endogenic angiogenic factor produced by TECs, and detachment of pericytes, which are located close to endothelial cells and play a role in maintaining vascular stability, occur after AKI and may contribute to this mechanism [13,17].
