Immunostaining of bacterial adhesions in the basopinacoderm. Both (a) Emβ-catenin and (b) EmVcl were detected at the interface of stress fibers and membrane pockets containing environmental bacteria. Neither (c) EmFAK nor (d) EmITGB were detected at these structures (but see text for further discussion of EmFAK) (a–d antibody staining only; a′–d′ antibody = green, DNA = blue, F-actin = red; scale bars = 10 µm]
