Figure 8. Immunofluorescence staining further verified the relationship between FABP6 expression and Treg infiltration. Immunofluorescence staining was performed on esophageal cancer specimens to examine FABP6 expression and Treg infiltration. The Treg lineage-specifying transcription factor FOXP3 served as a Treg marker. FABP6 (green), FOXP3 (red) and DAPI (blue) staining. Scale bar, 50 μm.
