Figure S3. Analysis of homing ability of Mx1-Cre⁻Apc^fl/fl and Mx1-Cre⁺Apc^fl/fl BM cells in lethally irradiated recipient mice. The proportion of CFSE⁺-labeled Mx1-Cre⁺Apc^fl/fl (red bar) and Mx1-Cre⁻Apc^fl/fl (blue bar) BM cells in recipient mice (mean ± SD; n = 5) was determined by flow cytometry, 6 h after injection.
