Figure Lengend Snippet: ID tissue exhibits higher densities of fibroblasts, macrophages, and microvessels compared to SC tissue. Immunofluorescence analysis comparing the expression of Vimentin (a fibroblast marker), CD68 (a macrophage marker), and CD31 (an endothelial cell marker) in ID and SC tissues. For each group, n = 3; data represent mean ± s.d.; ∗P < 0.05 and ∗∗P < 0.01.

Article Snippet: After antigen retrieval and blocking, sections were incubated overnight at 4 °C with primary antibodies targeting vimentin, CD68 (ABclonal, A20803), CD31 (R&D SYSTEMS, AF3628), HMGB1 (Cell Signaling Technology, 3935), HSP70 (ABclonal, A23457), NF-κB p65 (ABclonal, A19653), CD206 (Cell Signaling Technology, 24595), and FAPα (ABclonal, A23789 ).

Techniques: Immunofluorescence, Expressing, Marker
