Fig. 12From: Characterization of primary cilia during the differentiation of retinal ganglion cells in the zebrafishPrimary cilia dynamics in progenitors and differentiating RGC neuroblasts. In this diagram we summarize some of the main features of primary cilia behavior during early stages of retinal differentiation, based both on live fluorescence images of atoh7:gap-RFP/Arl13b-GFP expressing cells and on electron microscopy images. In the lower part of the figure the main ultrastructural characteristics found in apically localized primary cilia in early stages of development and of RGCs primary cilia by 48 hpf are also outlined.
