Chick Models and Human-Chick Organizer Grafts
2019The combination of affordability, large size, and ease of access at almost every stage of development renders the chick an excellent model organism for studying vertebrate development. Not only is it a great system in and of itself, but these qualities make it a great host for interspecies chimera experiments.

Ornithine transaminase in the liver of the chick embryo and in the young chick
Archives of Biochemistry and Biophysics, 1968Abstract Ornithine transaminase from chick liver was purified 100-fold. The pH optimum was 7.45. Michaelis constants were as follows: 0.01 m for l -ornithine, 0.0017 m for α-ketoglutarate, 0.05 m for oxaloacetate, and 0.1 m for pyruvate. α-Ketoglutarate had a protective effect on the enzyme.

NEWLY hatched nidifugous birds do not behave as if they recognized their own kind as such. On the contrary, they react in the same way to a very wide range of stimulus objects by approaching them and by giving ‘pleasure’ notes when near them. Thus the birds become attached to the stimulus objects.

Behavioural Processes, 1986
Chicks were trained to discriminate between two similar boxes according to their "relative" (i.e. in relation to each other) or "absolute" (i.e. in relation to the cage or other features of the environment) position. Results showed: (a) when the boxes were placed close together, learning on the basis of their relative position was much more rapid than ...

Nature, 1939 WORK on the evocation of neural tissue in vertebrate embryos by chemically prepared substances has hitherto been confined to the Amphibia1. But since in the induction of neural tissue in general the chick has shown considerable similarities to the newt, especially in the inducing activity of its organizer when coagulated2, and in the inducing activity ...

Phagocytosis in the chick blastoderm
Experimental Cell Research, 1962Abstract Chick blastoderms were cultured in vitro by the New [5] technique and treated with either colloidal gold or carmine solution. Considerably larger amounts of foreign particles were phagocytosed by the edge cells than by other parts of the blastoderm.

Movements of chick gastrulation
2020In birds as in all amniotes, the site of gastrulation is a midline structure, the primitive streak. This appears as cells in the one cell-thick epiblast undergo epithelial-to-mesenchymal transition to ingress and form definitive mesoderm and endoderm. Global movements involving tens of thousands of cells in the embryonic epiblast precede gastrulation ...

Pyrimidine biosynthesis in the chick
Archives of Biochemistry and Biophysics, 1970Abstract The capacity of the chick to synthesize pyrimidines was investigated in vivo with 14 C-carbonate. The incorporation of radioactivity into the uracil and cytosine isolated from the liver RNA was comparable to that found in the purine bases.

Ultrastructure of the chick thymus
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1973The ultrastructure of the normal thymus of the young chicken (Gallus domesticus) is described. Four main cell types, lymphoid cells, epithelial cells, macrophages and myoid cells, can be distinguished. The lymphocytes are more numerous in the cortex than in the medulla, and are quantitatively the most important component of the thymus.
