Figure 8. Immunophenotyping of MuMac-E8 cells.

Figure 8

MuMac-E8 cells were stained with fluorochrome-labeled monoclonal antibodies recognizing the surface marker proteins CD11b, F4/80 (A), CD14, and CD64 (B) in order to identify the functional phenotype of this cell line. It could be shown that MuMac-E8 cells in general express CD11b and that the majority of cultured MuMac-E8 cells express also F4/80 (91%). The number of CD11b+/F4/80+ cells increased following co-incubation with heat-killed S.E. (96%; A, right-hand panel). CD11b+/F4/80+ MuMac-E8 cells revealed high or moderate surface expression of CD14 or CD64, respectively. Moreover, the expression of both CD14 and CD64 on CD11b+/F4/80+ MuMac-E8 cells was additionally inducible by stimulation with Salmonella antigen (B).
