Figure 3. Expression of CD44 at 3 weeks after transplantation. CD44 expression was seen around the transplanted cells in the subretinal space. Higher expression of CD44 was seen in the retinal layers in the group of murine retinal progenitor cells (mRPCs) transplanted with chondroitinase ABC than in the mRPC group. A: GFP, B: CD44, C: DAPI, D: Overlay. A-D are from the group transplanted with mRPCs only. E: GFP, F: CD44, G: DAPI, H: Overlay. E-H are from the group transplanted with mRPCs combined with chondroitinase ABC. Scale bar: 50 um (D, H). Abbreviations: GCL, retinal ganglion cell layer; ONL, outer nuclear layer; SRS, subretinal space.
