Both hAEC and ECV administrations significantly decreased mortality, serum creatinine, number of apoptotic cells (TUNEL), and markedly increased tubular cell proliferation (Ki67 staining) and mRNA levels of the angiogenesis-related genes (Fgf, Hgf, Igf-1, Pdgf, and Vegf) after AKI in comparison to control group. This evidence concerns the gene VEGFA and acute kidney injury.
