Protein synthetic patterns of tissues in the early chick embryo.
Tissues dissected from early chick embryos were labelled in vitro with [35S]methionine, and their patterns of polypeptide synthesis investigated using the technique of two-dimensional (2-D) polyacrylamide gel electrophoresis. Apart from providing a preliminary description of the molecular changes associated with the processes of gastrulation and segmentation in the chick embryo, this study has ...
متن کاملPhosphorylating glycolysis in the early chick embryo.
From an ext,ensive series of experiments with whole embryos and with tissue mince, Needham and his coworkers (l-7) concluded that in the early chick embryo the phosphorylation route of glycolysis, the Meyerhof-Embden cycle, is imperfectly established. Because glycogen generally failed to be converted to lactic acid, they argued that the enzyme esterifying glycogen was absent or insufficient. Si...
متن کاملExpression patterns of engrailed-like proteins in the chick embryo.
The protein products of both of the identified chick engrailed-like (En) genes, chick En-1 and chick En-2, are localized in cells of the developing brain, mandibular arch, spinal cord, dermatome, and ventral limb bud ectoderm, as demonstrated by labeling with the polyclonal antiserum alpha Enhb-1 developed by Davis et al. (Development 111:281-298, 1991). A subpopulation of cephalic neural crest...
متن کاملThe Localization of / 3 - Glucuronidase in the Early Chick Embryo
I N vertebrate tissues there appears to be a connexion between /3-glucuronidase and the proliferation of cells. This connexion was first noticed by Levvy, Kerr, & Campbell (1948) when they were investigating the effect of toxic compounds on mouse-liver glucuronidase. The early stages of embryonic development are characterized by rapid proliferations of cells and it is, therefore, of some intere...
