Figure Caption

Fig. 9 Loss of plakoglobin results in fewer adhesion junctions and with an altered structure. (A and B) Electron microscopy of the intercalated discs of zebrafish embryo hearts at 72 hpf. (A) In control morpholino injected embryos, desmosomes (black arrowheads) were in series. (B) In morphant embryos, diffuse adhesion junctions (white arrowhead) were detected. (C) A table of indicating the cell–cell borders numbers, the number of adhesion junctions, and the number of each type of junction in control and morphant embryos. Unclassified indicates adhesion junctions that could not be definitively classed as adherens junction, desmosome or tight junction. N = 2 embryos per sample. Scale bar is 100 nm.
