Fig. 3.
Expression pattern of calbindin and other coexpressed calcium binding proteins in the ventral spinal cord throughout development. Axes originate from the central canal (0, 0) and indicate distance from the origin (in μm) along the dorsal-ventral axis (ordinate) and medial-lateral axis (abscissa). Gray outline in each panel illustrates the outer border of the spinal cord derived from the average of all sections within a particular lumbar domain from 5 animals. Color-coded dots (key provided in figure) indicate positions of calbindin-expressing neurons standardized to match the average dimensions of the cord at that age. Cells observed on both the right and left sides of the spinal cord from all five animals at each time point are combined in this figure and plotted on a right-sided ventral hemi-cord.
