Nitrogen Metabolism in the Chick Embryo
To determine the nature of the food material burned by the developing chick embryo use has been made of two methods in the past. The validity of the information to be derived from one of them-the measurement of the respiratory quotient-we shall presently have occasion to examine. The second and more reliable method is based upon direct analysis of the egg contents at various stages of developme...
متن کاملMetabolism of cholesterol in the tissues and blood of the chick embryo.
Three artificially inseminated laying White Leghorn hens were given 35-50 micro c of cholesterol-4-(14)C intravenously. Their subsequently produced eggs contained cholesterol-(14)C-labeled yolks. Some of the fertilized eggs were analyzed for cholesterol content and radioactivity. Other eggs were incubated until hatching. The specific activity of the cholesterol contained in the serum and tissue...
متن کاملMetabolism of ovomucoid by the developing chick embryo.
A glycoprotein resembling ovomucoid was purified from chorioallantoic membranes of 12.5 day chick embryos by a sequential procedure involving zinc chloride precipitation, hydroxylapatite chromatography, and ion exchange chromatography on DEAEand CM-cellulose. The resulting preparation was homogeneous as indicated by polyacrylamide gel electrophoresis at 3 pH values, isoelectric focusing, ultrac...
متن کاملA Chick Embryo in-Vitro Model of Knee Morphogenesis
Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...
