Common myeloid progenitor (CMP) progeny are present in bone marrow. At serial time-points after transfer of common lymphoid progenitors (CLPs) and CMPs, bone marrow (BM) cells from recipient mice were collected and analysed by flow cytometry. Each time-point includes four to six mice. (a) A representative pattern of IgM and CD43 expression on gated donor-type (Ly5·2⁺Ly5·1^–) B220⁺CD19⁺ B cells after transfer. The numbers in figure indicate the percentage of each population. (b) Percentage of CD43⁺ pro-B cells generated from progenitors. The data presented in figure are the mean ± standard deviation.
