Changes in somal growth and dendritic patterns of the retinal ganglion cells in the chicks and chick embryos.
Changes in the somal growth and dendritic patterns of retinal ganglion cells (RGCs) were studied in early chick embryos and post-hatching chicks by means of the retrograde axonal transport labeling with DiI. Branching patterns of the dendrites were relatively uniform on E8 (embryonic day 8) and became more complicated on E11. Variety of the branching pattern became plainly abundant after E14. On the other hand, somata of RGCs continued to grow until E14, corresponding the appearance of the central-peripheral gradient of the somal size. After E14, RGCs elaborated on the formation of the dendritic patterns as found in chick retina, and simultaneously the growth of somal sizes almost ceased.
