Low expression of PTX3 in human gastric cancer tissues and is associated with high M2/low M1 content. (A) PTX3 expression level in gastric cancer tissues and surrounding tissues were shown by immunohistochemistry (IHC). (B) PTX3 IHC staining scores in gastric cancer tissues (n = 30) and surrounding tissues (n = 30) were shown. (C) The protein expression of PTX3, CD206, CD86 in a human gastric cancer tissue array was tested by IHC. (D) Number of CD206+ and CD86+ cells per field in tissues with different levels of PTX3 expression. Representative pictures of IHC were shown (Scale bars: 50 μm) (*P < 0.05, **P < 0.01).
