Distribution of human ILCs in BRGSF mice and effect of Flt3L treatment. (A) Representative flow cytometry analysis of CD3⁻CD5⁻EOMES⁻CD7⁺CD127⁺ innate lymphoid cells in spleen, liver, and lung and CD3⁻CD5⁻CD94⁻CD7⁺CD127⁺ cells in gut of an Flt3L-treated BRGSF mouse. (B) Comparative quantification of ILCs in spleen, lung, liver, and gut of BRGSF mice treated or not with Flt3L as a percentage of hCD45⁺ cells (top) and total number of cells (bottom). Composite data from of 14 mice per condition in 4 experiments are shown. Each dot represents 1 mouse. Numbers in plots represent frequencies within gates.
