Figure 8.

Three regions in a 17 WG Retina. The inner retina at 17 WG has nerve fiber layer (}) with blood vessels (arrowhead), a putative ganglion cell layer ({), and an inner neuroblastic layer ([). Regional expression patterns show the diffuse distribution of VEGF₁₆₅ in the nerve fiber and putative ganglion cell layer. Nerve fiber VEGF₁₆₅ is apparent in (E). Cell-associated VEGF₁₆₅b is more intense in advance of forming blood vessels and weakest in the vascularized peripapillary area. (APase reaction product)
