Immunostaining of dorsal adhesions. Neither (a) Emβ-catenin, (b) EmVcl, nor (c) EmFAK were detected at mesohyl-interfacing plaques (white arrowheads) of dorsal adhesion stress fibers. Visible staining of Emβ-catenin corresponds to a bacterial adhesions (black arrowhead) and of EmVcl corresponds to ventral adhesions (Asterisk). In contrast, d EmITGB was highly enriched at dorsal adhesions (a–d antibody staining only; a′–d′ antibody = green, DNA = blue, F-actin = red)
