Fig. 5From: Hypoproliferative human neural progenitor cell xenografts survived extendedly in the brain of immunocompetent ratsRepresentative pictures show a subpopulation of microglia that upregulate MHC-II expression in response to the surviving human graft. A MHC-II upregulation specifically observed in microglia. B The enhanced MHC-II expression by LPS challenge. C Population data showing that the host MHC-II expression remains relatively low level with no changes over time (ANOVA, P > 0.05). N = 3 biologically independent samples.
