CD47 expression in patients with ESCC. (A) Reverse transcription-quantitative polymerase chain reaction was used to measure the CD47 mRNA expression in cancerous and non-cancerous tissues collected from patients with ESCC (n=14). The horizontal lines indicate the mean value. (B) Representative images of immunohistochemistry staining of ESCC tissue with anti-CD47 antibodies (brown). Representative case of CD47-positive (right) and -negative (left) tissue. *P<0.05. CD, cluster of differentiation; ESCC, esophageal squamous cell cancer; RQ, relative quantity.
