Immunostaining of cell–spicule junctions. a Emβ-catenin and b EmVcl localize to cell junctions at the interface with spicules (dotted lines mark spicules). c EmFAK was possibly enriched at these structures, but only marginally above background levels (arrowheads), whereas d EmITGB was not detected at all (a–d antibody staining only; a′–d′ antibody = green, DNA = blue, F-actin = red; scale = 10 µm)
