Phenotype of CBDC. Lin⁻ (CD3, CD11b, CD14, CD16, CD19, CD34, CD56, and glycophorin A negative) enriched CB cells were double labeled with the MoAb specific for the molecules indicated and anti–HLA-DR. Lin⁻/HLA-DR⁺ CBDC were gated electronically. The quadrants were set according to isotype controls.
