Figure 6. mPins protein localization in postnatal mouse retina by immunohistochemistry. mPins protein localization is shown in the developing mouse retina at postnatal stages P3 (B), P5 (C), and P12 (D). At stages P3 (B) and P5 (C), mPins protein is detected primarily in the ganglion cell layer (GCL) and the neuroblastic layer (NbL). In the retina at stage P12, mPins is observed in the GCL, the inner nuclear layer (INL), and the outer nuclear layer (ONL; D). Moreover, in the INL, mPins labeling was found to be more intense on either side of this layer than in its center (asterisks). Immunolabeling is also detected in the inner plexiform layer (IPL), but no labeling is observed in the outer plexiform layer (OPL) or in the photoreceptor segments (PS; D). A shows Diaminobenzidine (DAB) immunonegative control.
