Tissue specificity of myocardial glycopeptides synthesized during early embryonic development.
[3H] Glucosamine-labeled glycopeptides synthesized by hearts from stage 14-16 chick embryos were separated on DE-52 by ion-exchange chromatography and compared to those synthesized in other parts of the embryo at the same stage. Relatively few molecular species were present in all tissues, and they appeared closely homologous. There were no glycopeptides unique to any embryonic region examined, suggesting that tissue specificity may result from quantitative rather than qualitative differences in glycopeptides.
