Figure 5. Expression of marker proteins of HCE cells at passage 101. A: western blot, showing the positive expression of COL4A2 and FLK1, and negative expression of vWF and keratin 12 of HCE cells. B: immunocytochemistry, showing the positive expression of NSE. COL4A2, type IV human collagen α2 polypeptide; FLK1, human vascular endothelial growth factor receptor-2; vWF, human von Willebrand Factor; keratin 12, human keratin 12; NSE, neuron specific enolase.
