Figure 3 Immunohistochemistry of pigment epithelium-derived factors (PEDF) in three groups. A: Pigment epithelium-derived factors (PEDF) immunohistochemistry (IHC) plot in normal group (IHC × 100); B: PEDF immunohistochemistry plot in normal group (IHC × 200). In the normal group, the nuclei of the study cells were brownish yellow, the number of positive cells was more than 75%, and the expression was strongly positive (+++); C: PEDF immunohistochemistry plot in adenoma group (IHC × 100); D: PEDF immunohistochemistry plot in adenoma group (IHC × 200). In the adenoma group, the nuclear color was mainly yellow, the number of positive cells was more than 75%, and the expression was moderately positive (++); E: PEDF immunohistochemistry plot in colorectal cancer (CRC) group (IHC × 100); F: PEDF immunohistochemistry plot in CRC group (IHC × 200). In the CRC group, the nucleus was almost uncolored, the number of positive cells was 0%, and the expression intensity was negative (-) expression. PEDF: Pigment epithelium-derived factors.
