Effect of Chloromycetin and Streptomycin on Embryonic Tissue Growth in In vitro Tissue Culture

Abstract

Using 9-day chick embryo heart in roller tubes the effects of chloramphenicol and streptomycin were studied. Growth of normal embryonic tissue was completely inhibited by concns. of 90,000 and greater [mu]g./ml. of streptomycin. Growth was partially inhibited by concn. of 480 [mu]g./ml. through the highest concn. of chloramphenicol tested. A slight but consistent increase in growth was observed in concns. of 240 [mu]g./ml. of chloramphenicol.
