Fig 5. In vivo longitudinal detectability of grafted monocytes and MΦ using MRI at 9.4 T.

Fig 5

(A) Qualitative MR images (MGE sequence) of graft titration with different numbers of SPIO labelled monocytes (WT), with the cell numbers indicated below both hemispheres, n = 1. Transplanted cells are visible as small hypointense clusters. (B) Imaging time course of transplanted WT monocytes and MΦ for days 1, 3 and 12 post transplantation. Left hemisphere 1500, right hemisphere 500 cells, n = 1 per cell type. (C) Representative PB staining of brain tissue section indicating grafted monocytes as PB+ (blue) cells. Scale = 50 μm.
