Sagittal sections of adult hearts from Centrophorus granulosus (a), Leucoraja circularis (b), Scyliorhinus canicula (c), Polypterus senegalus (d), Acipenser naccarii (e), Osteoglossum bicirrhossum (f), Danio rerio (g) and Mesocricetus auratus (h) immunolabeled with A4.1025. The signal is restricted to the atrial (A) and sinusal (SV) myocardium in chondrichthyans (a, b, c), to the sinusal (SV), atrial (A) and conal (C) myocardium in polypteriforms (d) and is present in all the myocardial segments of acipenseriforms (e), teleosts (f, g) and mammals (h). B, bulbus arteriosus; V, ventricle. Scale bars: 1 mm
