Immunostaining of cell–cell junctions in the apical endopinacoderm. Emβ-catenin, EmVcl, EmFAK and EmITGB were detected at probable adhesion plaques where F-actin tracts align between adjacent cells (white arrowheads). Low-intensity staining of EmITGB was also detected at the cell cortex (black arrowheads) of the apical exopinacoderm (a–d antibody staining only; a′–d′ antibody = green, DNA = blue, F-actin = red; scale = 10 µm)
