Comparative kinetics of embryo development
Bulletin of Mathematical Biology, 1993A model of embryo energetics was fitted to data from the literature for species as different as snails and mammals. The model is based on assumptions about energy uptake, storage and utilization. It describes the animal by two state variables: volume and energy storage. Embryo weight is taken to be proportional to volume, yolk weight to energy storage,

Early development of the chick embryo
Journal of Morphology, 1993AbstractThe ultrastructure of the early chick embryo was investigated, using scanning (SEM) and transmission electron microscopy (TEM). Eggs were obtained from the shell gland by injecting hens intravenously with a synthetic prostaglandin or arginine vasopressin.

The myosin of developing chick embryo
Archives of Biochemistry and Biophysics, 1969Abstract Two components were present in myosin preparations from the early stage of chick embryo. The sedimentation coefficient ( s 20, w 0 ) were 3.4 and 6.7, respectively. The two components were separated with ammonium sulfate. Both components had ATPase activity of myosin type as rabbit myosin. The specific ATPase activity of the 6S component

The Early Development of Human Embryos
Journal of Medicine and Philosophy, 1985The development of the human embryo from the time of fertilization through the eighth post-fertilization week is described for medical policy purposes. During pre-implantation stages, differentiation occurs between precursors of embryonic and extra-embryonic structures. During implantation formation of a fore-hind axis begins within the inner cell mass.

Antigens in the Developing Newt Embryo
Nature, 1951IMMUNE sera have been prepared in rabbits against isolated tissues of stages of embryonic Triton alpestris. The tissues used were: whole gastrula (crescent-shaped blastopore), archenteron roof, and ectoderm (both from early yolk-plug stages). The antisera were used both for interfacial precipitin tests and, diluted, as stock culture media of the same ...
