Fig. 8From: Long-term leukocyte reconstitution in NSG mice transplanted with human cord blood hematopoietic stem and progenitor cellsMaturation/differentiation of B cells in spleen. B cells in spleen were analyzed for maturation. Gating strategy is shown in Additional file 5: Figure S5B. B cell subpopulations were defined as follows: Pro/Pre/Imm/Tra (pro-B, pre-B, immature, transitional B cells) = CD38hiCD24hi, mature = CD38intCD24int, memory = CD38loCD24hiBack to article page
