Qualitative examination of the host anatomical response to the presence of hNPCctx or hNPCctx - GDNF revealed substantial preservation of the photoreceptor outer nuclear layer (ONL) overlying all subretinal donor cells (Figure 5E and F), with
photoreceptor rescue gradually declining outside the distribution of the transplanted cells (Figure 5E and G).
Human neural progenitors survive as two distinct populations within the retina and promote
photoreceptor rescue.
