Demonstration of atrial natriuretic peptide immunoreactivity and ultrastructurally related secretory granules in myoblasts of the chick myotome.


In this study, an ultrastructural and immunohistochemical examination was carried out on the presence of an 'atrial-natriuretic-peptide (ANP)-like factor' in the myoblasts of the brachial myotome of chicken embryos at Hamburger and Hamilton stages 17 +/- to 19. The results of the immunohistochemical study indicate that, at these stages of their development… (More)
