Preliminary study correlating CX3CL1/CX3CR1 expression with gastric carcinoma and gastric carcinoma perineural invasion

Figure 1 CX3CR1 expression. A: CX3CR1 expression (× 200) in perineural invasion (PNI)-positive tumour cells and nerve cells; B: CX3CR1 expression was present in tumour cells and absent in nerve cells from the PNI-negative group (× 200).

Figure 2 CX3CR1 expression levels in the perineural invasion-positive group (A) and perineural invasion-negative groups (B). a and b are from tissues adjacent to the tumour, while c and d are tumour tissues, and β-actin is shown below.
