VEGFA and hepatocellular carcinoma: An extensive survey of putative hepatic stem/progenitor cell biomarkers, namely CK19 (cytokeratin 19), CD133, Nestin and CD44 conducted by Yang and collogues [42] using HCC-TMA revealed that high HSC/HPC profile along with high VEGFA (vascular endothelial growth factor A) levels and increased MVD (micro vascular density) had significant lower OS (overall survival) and RFS (recurrence free survival).
