Jmg. Galvez et al., LATE EVENTS IN THE MIGRATIVE BEHAVIOR OF THE RETINAL GANGLION-CELLS -A GOLGI-STUDY IN THE CHICK RETINA, Histology and histopathology, 8(4), 1993, pp. 645-649
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 compu
ter-assisted image processing. Our findings indicate that some ganglio
nar soma are still located in the inner nuclear layer (INL) while othe
rs pierce the inner plexiform layer (IPL), exhibiting morphological ad
aptation of their perikaryon. The changing morphology of these delayed
retinal ganglion neuroblasts seems to be due to the late translocatio
n of the cell perikaryon to the GCL. This late migrative displacement
of the ganglionar population is discussed in relation to the presence
of displaced ganglion cells of Dogiel.
