CD8 (OX8) immunoreactivity in striatum. (A) Little or no CD8 staining was observed in PBS control animals. (B-C) Few CD8⁺ cells were detected in and around the injection tracts of Wistar MSC-treated and ACI MSC-treated animals (same rats shown in Fig. 2). (D) The numbers of CD8⁺ (OX8) cells were significantly increased in the MSC-transplanted groups compared with PBS-injected controls (graph shows means ± SEM;*p < 0.05). Scale bars = 80 μm.
