[Effect of concanavalin A on the development of blastulae in Pleurodeles waltlii (Amphibia, Urodeles)]. 1977

J C Boucaut, and B Bernard, and M Aubery

The effect of concanavalin A (con A) on Pleurodeles waltlii blastulae was studied by incubating the eggs in presence of lectin. It was found that the protein exercised an inhibitory effect upon morphogenesis. This inhibition was concentration dependent. In certain cases, the inhibitory effect of con A was attenuated by alpha-D-methyl-mannose (0,05 M).

UI MeSH Term Description Entries
D008766 Methylmannosides Mannosides formed by the reaction of the hydroxyl group on the anomeric carbon atom of mannose with methyl alcohol. They include both alpha- and beta-methylmannosides. Methylmannopyranosides
D001755 Blastocyst A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.
