Biodistribution and persistence of xenogeneic MSCs in NSG mice. a Representative bioluminescence images showing the biodistribution and persistence of the luminescence produced by FireFly- or NanoLuc-MSC,WJ at 48 h, one-two weeks, and six weeks after treatment. b Representative images of human COXIV immunostaining in longitudinal sections of tibias six weeks after treatment. Black arrows indicate positive cells. Images in the right column are a magnification of images in the left column. Scale bar: 100 µm. WT wild-type; FFly FireFly; NLuc NanoLuc
