Expressions of BPTF, VEGF, VE cadherin and CD31 were detected in postoperative clinical tissue samples of human lung adenocarcinoma. a Fresh postoperative cancer tissue and para-cancer tissue samples of 10 patients with lung adenocarcinoma were randomly selected, and the expression levels of BPTF and VEGF were detected by immunofluorescence method, among which two representative cases were selected. b The expression of angiopoiesis-related CD31 and VE cadherin was detected by the same method, and two representative cases were selected. c Western blot was used to detect the expressions of BPTF, VEGF and VE cadherin in cancer tissues and adjacent tissues of 10 patients with lung adenocarcinoma. “N” represents relatively normal tissue adjacent to cancer, and “T” represents tumor tissue
