Immunohistochemistry of cortical brain slices. (a) Green signal is microglia stained with fluorescein isothiocyanate-conjugated IB4 in the brain of mouse treated with PCP who underwent sham transplantation. (b) Red cells are human MSCs pre-labeled with PKH-26. (c–e) Evaluation of rejection using merged photo of PKH-26-labeled MSCs and microglia staining. IB4, Bandeiraea simplicifolia isolectin B4; MSCs, mesenchymal stem cells; PCP, phencyclidine.
