Figure 12From: A stochastic model for retinocollicular map developmentThe choice of receptor/ligand expression profiles. A, Density of ephrinA ligands in SC obtained from RNA hybridization [10]. B, Density of EphB receptors in retina from RNA hybridization [20]. C, density of RGC in retina [39]. D, Density of EphA receptor per cell, obtained by dividing B by C. Vertical axes in A, B, and D are in arbitrary units. Dashed lines show the exponential approximations used in this study.Back to article page
