The isolated Hensen's nodes of chick embryos (stage 4 after Hamburger and Hamilton) were cultivated in organotypic cultures after the treatment with 0.5 mM solutions of cAMP and cGMP. Both the control and treated explants were characterized by a wide variability of differentiation of various tissue rudiments. cGMP inhibited reliably the differentiation of notochord. At the ultrastructural level the control and cAMP-treated cultures were characterized by an increased autophagia whereas the treatment with cGMP inhibited the yolk utilization and resulted in the appearance of vast regions of partial necrosis. |
