Vascular maturity-related protein expression after Ang-1 treatment. (a) Immunohistochemical staining of ZO-1, occludin, VE-cadherin, and Connexin40 in the four groups was performed. Several proteins are expressed on the envelope of endothelial cells (black arrow), × 200. (b) The relative quantification of ZO-1, occludin, VE-cadherin, and Connexin40 in four groups. △ represents P <0.05 compared with the control group, represents P <0.05 compared with the Ang-1 treatment group, and N/D represents no expression.
