Delay of PRC degeneration in RCS rat retinas 90 days after transplantation. (A) Retina of a 21-day-old rat before the beginning of PRC degeneration. (B) Dystrophic retina of a 63-day-old rat. (C) PRC rescue 90 days after transplantation in an eye that received microencapsulated FGF18. Note the microcapsule-proximal retina which comprises five or six PRC layers (arrow). (D) P16-filled microcapsule close to a dystrophic retina 90 days after transplantation. The PRC layer is indicated by arrows. (Sections were 16 μm thick; toluidine blue staining; Bar = 20 μm.)
