JNK3 is absent during mitosis of retinal progenitor cells.

<p>Representative confocal photomicrographs of immunohistochemistry for JNK3 (red) and phospho-histone-H3 (green) in sections of retinal tissue maintained for 3 hours <i>in vitro</i> either in absence (A - CTR) or presence of taxol (B - TAX). The sections were counterstained with DAPI (blue). Cells stained for JNK3 were found only in the ganglion cell layer (GCL), in the immature inner nuclear layer and in a few cells in the NBL. Arrows indicate examples of JNK3 positive cells. Scale bar: 20 µm. CTR - control; TAX - taxol; GCL - ganglion cell layer; NBL - neuroblastic layer.
