Using autoradiographic technique, we have studicd DNA synthesis in normal embryonic chick lens epitheliuni and after experimental lens rotation. Analysis of the autoradiograms clearly demonstrates that when the lens priniordium was rotated 180". so that lens epithelium was placed facing the interior of the optic cup. the lens epithelial cells...

The effect of ethanol on the cerebellar cortex of chick embryos was studied in semi-thin sections of material prepared for electron microscopy. The embryos were injected with ethanol on the 3rd or 6th day of incubation and observed until days 13, 15, 17 and 21 of development. A decrease was seen in the number of germinal cells generated,...

We report the morphological differences of Müller cells in relation to their topography, using the Golgi method. Müller cells in the central retina are long and slender, with numerous inner prolongations. In the peripheral retina, the morphology of the Müller cells adapts to the reduced thickness of the retina1 layers. In this zone, they are...

The final displacement of the prospective ganglion neurons toward the ganglion cell layer (GCL) has been analyzed in chicken embryos during days 8 and 9 of incubation with the help of the Golgi method and computer-assisted image processing. Our findings indicate that some ganglionar soma are still located in the inner nuclear layer (INL) while...

Surnrnary. The migration process of the ventral horn in chick embryo spinal cord cells has been studied between 2.5 and 5 days of incubation (HH-17, HH-26), using the Golgi technique. Two different migratory modes are observed. Type 1.- Migration by nucleus translocation. Most of the ventral horn motor neurons migrate by nucleus translocation...
