Coloboma Of The Iris

When Guyer & Smith (1918, 1924) subjected pregnant rabbits to active and passive immunization with lens proteins, it was noted that a high percentage of the new-born showed lens anomalies and other ocular changes such as microphthalmia and coloboma of the iris. Though these experiments seem to indicate that antibodies circulating in the maternal circulation may interfere with embryonic development, the results of this work have subsequently been questioned, since neither Finlay (1924), Huxley & Carr-Saunders (1924), nor Flickinger, Levi, & Smith (1955) were able to produce any eye abnormalities with lens antibodies. Recently, it has again been suggested, that tissue antibodies may cause congenital defects based on antigen-antibody interaction in the developing embryo (Brent, Averich, & Drapiewski, 1961; Gluecksohn-Waelsch, 1957; Miller, 1958; Barber, Willis, & Afeman, 1961).

Histochemical Evidence

In the egg of Drosophila the distribution of sulphydryl and ribonucleic acid compounds has no apparent connexion with the dorso-ventral organization, contrary to the situation found in the amphibian egg. Histochemical evidence suggests that the nucleic acid metabolism of the Drosophila egg may be similar to that of the chick embryo. During embryogenesis the contraction of the germ band can be considered as an important morphogenetic stage which marks the beginning of the histo-differentiation of all larval structures.

The Brain

Oligodendrocytes are the myelin-forming cells in the central nervous system. In the brain, oligodendrocyte precursors arise in multiple restricted foci, distributed along the caudorostral axis of the ventricular neuroepithelium. In chick embryonic hind-, mid- and caudal forebrain, oligodendrocytes have a basoventral origin, while in the rostral fore-brain oligodendrocytes emerge from alar territories (Perez Villegas, E. M., Olivier, C., Spassky, N., Poncet, C., Cochard, P., Zalc, B., Thomas, J. L. and Martinez, S. (1999) Dev. Biol. 216, 98–113). To investigate the respective territories colonized by oligodendrocyte progenitor cells that originate from either the basoventral or alar foci, we have created a series of quail-chick chimeras. Homotopic chimeras demonstrate clearly that, during embryonic development, oligodendrocyte progenitors that emerge from the alar anterior entopeduncular area migrate tangentially to invade the entire telencephalon, whereas those from the basal rhombomeric foci show a restricted rostrocaudal distribution and colonize only their rhombomere of origin. Heterotopic chimeras indicate that differences in the migratory properties of oligodendroglial cells do not depend on their basoventral or alar ventricular origin. Irrespective of their origin (basal or alar), oligodendrocytes migrate only short distances in the hindbrain and long distances in the prosencephalon. Furthermore, we provide evidence that, in the developing chick brain, all telencephalic oligodendrocytes originate from the anterior entopeduncular area and that the prominent role of anterior entopeduncular area in telencephalic oligodendrogenesis is conserved between birds and mammals.

Larval Skeleton

The literature on the notochord, a structure characteristic of all vertebrates, is very extensive, due to the phylogenetic importance of this organ, its role in early embryonic development, and its central position in the developing vertebral column. As early as 1834 the notochord tissue was described by Müller as being similar in appearance to the parenchyma of plants. Surprisingly, however, in the chick embryo, which is so widely used by embryologists, its development has not very often been the subject of descriptive or experimental investigations. From the early days most work on this fundamental organ was done on fish and amphibians, probably because the notochord in lower vertebrates is more suitable for investigations, as it persists longer, carrying out its function as an embryonic and larval skeleton.

This is the first study of the role of BRE in embryonic development using early chick embryos. BRE is expressed in the developing neural tube, neural crest cells, and somites. BRE thus plays an important role in regulating neurogenesis and indirectly somitogenesis during early chick embryo development.

Chick Development

We describe a technique for removing and growing chick embryos in culture that utilizes relatively inexpensive materials and requires little space. It can be readily performed in class by university, high school, or junior high students, and teachers of any grade level should be able to set it up for their students. Students will be able to directly observe the chick’s development from 3 days post-fertilization to the point at which it would normally hatch. Observing embryonic development first hand, including the chick embryos’ natural movements, gives students a full appreciation for the complexity and wonder of development. Students can make detailed observations and drawings, and gain understanding of important principles in developmental biology. Finally, we suggest various ways in which this project can be adapted to allow students in advanced classes to design and implement their own projects for investigating teratogenic effects on development using the ex ovo model of chick development.

Blood Contamination

Alpha-fetoprotein (AFP) is a major globulin of the embryonic serum of mammals, birds, and other vertebrates. It is synthesized chiefly by the liver and/or the yolk sac. The aim of this work was to confirm the occurrence of AFP in the chorioallantoic membrane (CAM) from 14-day chick embryo. AFP had previously been detected by immunoelectrophoresis in CAM extracts under the suspicion that it could be a mere artifact resulting from blood contamination. The immunohistochemical study of the CAM carried out for this purpose revealed the protein to be solely located in the mesodermal layer. The joint use of organ culture and immunoperoxidase techniques has enabled us to find evidence for the synthesis of AFP in the cells of this layer. These results confirm the occurrence of such a significant carrier globulin to embryonic development in one more tissue that can be added to the short list of AFP-producing tissues.
