Fig. 3From: Adult human periodontal ligament-derived stem cells delay retinal degeneration and maintain retinal function in RCS ratsHuman PDLSC transplantation enhanced ERG b-wave amplitude. a Representative scotopic ERG recordings from untreated RCS rats (W/O) and RCS rats injected with PBS (vehicle) or hPDLSCs at 2, 4, and 8 weeks post transplantation. b The b-wave response amplitudes of the PDLSC-injected group were significantly higher than those of the untreated or PBS-injected groups at 2, 4, and 8 weeks post transplantation. n ≥ 4 eyes per group at each time point. *p < 0.05.
