Objective To explore the expression of CD105 protein in esophageal squamous cell carcinoma and it＇s relationship with P53 protein. Methods Using streptavidin biotinperoxidase （SP） method, the expression of CD105 protein and P53 protein in esophageal squamous cell carcinoma were examined in normal esophageal tissues （n=10） and esophageal squamous cell carcinoma tissues（n=86）. Results The expression positive rate of CD105 protein was 74. 4%（64/86） in esophageal squamous cell carcinoma , 0% in normal esophageal epithelium. Expression positive rate of CD105 protein was 66. 1%（37/56） in early stage （stage Ⅰ-Ⅱ ）, 90.0% （27/30） in later stages （stage Ⅲ-Ⅳ ）. The expression of CD105 protein were bly associated with P53 protein（P〈0. 05）. Conclusion CD105 protein may participate in the onset and progression of esophageal squamous cell carcinoma. CD105 protein could he a new diagnostic /therapeutic target in esophageal squamous cell carcinoma.
