...J.S. van Twest; A. Paulsen; B.S. Spooner Chick precardiac tissue explants were cultured on the 8-day mission of STS-60, space shuttle Discovery. Development of in vitro cultures of precardiac chick tissue from embryo stages 5 through 8 (H-H) were initiated during orbit and were terminated after...

...S.M. Oliani; A.P. Girol; R.L. Smith Mast cells are present in the eye of chick embryos from the 14th day onward, displaying metachromatic granules, mainly in the iris anterior surface and pectinate ligament. Ultrastructurally these cells show electron-dense granules and a few thin and short...

... and morphometry. HNK-1-labelled cells advanced rostrocaudally in the gut of quail embryos (to the duodenum by stage HH 21 to the umbilicus by HH 25, to the ceca by HH 27, to the cloaca by HH 33). The timetable in chick embryos appeared to be slightly slower, but neural cells were obscured by background...

... asked whether or not the activities of the E-cadherin gene could cause a definitive embryonic mesenchyme to trans-differentiate into an epithelial phenotype. Primary corneal fibroblasts from 6-to 7-day-old chick embryos were cotransfected by impact loading with plasmids containing E-cadherin and Neor...

...J. Männer; W. Seidl; G. Steding It has been proposed that the cervical flexure of vertebrate embryos arises from the normal morphogenesis of the heart. This hypothesis is based on experiments in which the heart tube is removed or disrupted in early chick embryos. It has been reported...

...A.S. Chan The ultrastructure of the stromal cells of the thymuses of chick embryos from the 13th to 19th day of incubation was investigated. At the 13th day, the non-lymphoid elements consist mainly of undifferentiated and epithelial cells. The dominant cystic cells are organized to form intra...

These complexes are extractable from...

To determine the true origin of the third parathyroid (parathyroid III) gland in the chick embryo, pieces of the third...

Trabeculation appears to be the expression of three closely interrelated events: the formation of endocardial outgrowths that eventually...

...A. Quesada; C. Chmielewski; A. Espinar; J. Ambrosiani; F.A. Prada Ultrastructurally, two different bipolar cell types can be distinguished in the retina of the chick embryo: one pale or electron-lucent and the other dark or electron-dense. The different electron density was seen over the whole cell...

The embryos were divided for study into three groups: (I) before the fusion of the paired cardiac primordia...
