Figure 5: Flow cytometry analyses.

The levels of MHC-class I (blue) and II (red) showed no obvious intergroup differences among ESCs, iPSCs, NSCs, iNSCs and MSCs. Moreover, the levels of MHC-class I and II in these stem cells were lower than those in syngeneic splenocytes (n = 3/group). Isotype antibodies were used as controls (black).
