Kurzbeschreibung (Abstract)

Whole chick embryo eyes between embryonic day 10.5 and 12 (E10.5-E12) were incubated in a solution of Lucifer Yellow and examined in frozen sections. Starting around day 10.5, brightly stained cells were observed in the innermost part of the inner nuclear layer. Their size, shape and location suggest that most of them represent a subclass of amacrine cells. A distinct spatio-temporal development of Lucifer Yellow-staining of this subpopulation of cells within the inner nuclear layer between E10.5 and E12 is revealed in detail using 3-dimensional models of Lucifer Yellow-stained eyes. The staining can be first observed at a specific location at the ventro-posterior side not far from the fundus. It then spreads radially in a complex pattern reaching the ora serrata first on the ventro-posterior side, then sequentially reaching into the dorso-posterior, the ventro-anterior and finally the dorso-anterior quadrants of the retina. Our results suggest that a horizontal (posterior-anterior) axis and a vertical (ventro-dorsal) axis function as a coordinate system during differentiation of the tissue. We conclude that there are precise spatio-temporal patterns of Lucifer Yellow-staining which most probably reflect spatio-temporal patterns of cell differentiation within the chicken retina. The correlation of these findings with other data on spatio-temporal patterns during differentiation of the chicken retina is discussed.
