Figure 7. Abundant FcεRI γ-chain expression and IgE binding in subconfluent human intestinal tumor cell lines.

Figure 7

Immunofluorescence staining of (A, D, G, J) FcεRI β- and (B, E, H, K) FcεRI γ-chain are performed in (A–C) subconfluent and (D–F) confluent Caco2/TC7 and in (G–I) subconfluent and (J–L) confluent HCT-8. (C, F, I, L) According to the expression pattern of FcεRI in the subconfluent cells, IgE binding is observed exclusively in subconfluent, non-mature intestinal cells. The blue fluorescence DAPI staining indicates the nuclei. Original magnification ×40.
