Development of Feather Keratin during Embryogenesis of the Chick
The development of keratin in 9 to 17 day embryonic chick feathers has been studied by x-ray diffraction and cytochemical methods. The x-ray diffraction pattern given by the 9-day feathers contains none of the features seen in the adult pattern. In the 10 to 11 day patterns, besides two diffuse rings centered at 4.7 A and 10 A, two sharp, rather weak rings are seen at 35 A and 4.2 A with slight...
متن کاملOct1 regulates trophoblast development during early mouse embryogenesis.
Oct1 (Pou2f1) is a transcription factor of the POU-homeodomain family that is unique in being ubiquitously expressed in both embryonic and adult mouse tissues. Although its expression profile suggests a crucial role in multiple regions of the developing organism, the only essential function demonstrated so far has been the regulation of cellular response to oxidative and metabolic stress. Here,...
متن کاملZebrafish cyclin E regulation during early embryogenesis.
Cyclin E cDNA, cloned from a zebrafish embryonic cDNA library, was used for analysis of cyclin E regulation during early embryogenesis. During the rapid cell cycles of the early cleavage stage, which lacks a G1 phase, the cyclin E mRNA, protein, and associated H1 kinase activity were found to be constitutive, in contrast to their reported cyclic behavior during the cycle of cultured mammalian c...
متن کاملCell cycle regulation during early mouse embryogenesis.
Elaboration of a multicellular organism requires highly efficient coordination between proliferation and developmental processes. Accordingly, the embryonic cell cycle exhibits a high degree of plasticity; however, the mechanisms underlying its regulation in vivo remain largely unknown. The purpose of this review is to summarize the data on cell cycle regulation during the early mouse embryonic...
متن کاملExpression of CAP2 during early Xenopus embryogenesis.
We have cloned and characterized a second member of the Xenopus CAP (cyclase associated protein) gene family. xCAP2 demonstrates greater restriction of expression than its homolog, xCAP1, and is differentially expressed throughout early embryogenesis. Although present as a maternal transcript, CAP2 comes to be expressed in the anterior-most mesoderm/endoderm during late gastrulation, in paraxia...
