Fig. 8From: Adult human periodontal ligament-derived stem cells delay retinal degeneration and maintain retinal function in RCS ratsFluorescence microscope images of retinal sections injected with hPDLSCs at 8Â weeks post transplantation. Retinal sections were double-stained with human antigen TRA-1-85 (b) and recoverin (c), with DAPI counterstaining (a) which showed no colocalization (d). Arrowheads indicate migrating hPDLSCs.
