Analysis of SCID mice transplanted with HFL. Four months after transplantation of irradiated SCID mice (n = 9 mice) with HFL cells: (A) mononuclear cells isolated from the BM and cells in the lymphoid gate were analyzed by flow cytometry for the expression of human CD45, CD34, CD19, and CD20. (B) Mononuclear cells isolated from the BM and cells in the myeloid gate were analyzed by flow cytometry for the expression of human CD45, CD33, CD11b, and CD14. (C) Mononuclear cells isolated from the PB were analyzed by flow cytometry for the expression of human CD45, CD20, and CD11b.
