Distribution and fate of Mreg_UKR in NSG mice. Recipient mice were given 5 × 106 viable M regs or vehicle-only by slow intravenous injection. The tissue distribution of M regs was then assessed on days 1 to 7 post-injection by flow cytometry. Human M regs defined by expression of human CD45, CD11b and HLA-DR were detected in lung, blood and liver at all timepoints. Although the engrafted M regs remained CD14-, CD16 expression was regained by day 1. Data are representative of at least two animals per timepoint from at least two independent experiments.
