Coinfusion of mature CD14⁺ or CD19⁺ cells and CLL cells obviate necessity for preconditioning with hCD34⁺ cells. (A) Two examples shown (7 CLL samples, in 37 mice with at least 10 per group). See “Cotransfer of mature allogenic APCs supports CLL proliferation” for experimental details. (B) CLL 1235 as an example of preconditioning with hCD34⁺ cells or CD14⁺ cells from the same CB sample equally supporting CLL growth (3 CLL samples, minimum 6 mice per group).
