Figure 4.

Postnatal retinal development morphology of BN-H and BN-J rats. From P1 to P8, the neuronal layers are segmented into inner neuroblastic (INbL) and outer neuroblastic layers (ONbL) both in BN-H (A, B) and in BN-J (D, E) rats. However, from P8 to P15, whereas inner and outer segments (IS and OS) elongate normally in the BN-H retina (C), focal areas without segment elongation and persistent neuroblastic nuclei (circled areas) are observed in the BN-J retina (F). Dilated capillaries can be observed in the INL of BN-J retina (F, arrow). GCL, Ganglion cell layer. Scale bar, 20 μm.
