Overview of six distinct stages of developing and aging in mice eyes and retinas. The body length of the mice and eye size gradually increased from CE to OP. In HE stained retinal sections, after retinal progenitor cells differentiation to multiple retinal cells, retina with different layers were gradually formed from CE to SP. CE: close eye period; SP: suckling period; PP: puberty period; AP: adult period; MP: middle period; OP: old period; d: days; w- weeks; HE: hematoxylin and eosin; GCL: ganglion cell layer; NBL: neuroblast layer; INL: inner nuclear layer; ONL: outer nuclear layer.
