Percentage of donor nucleated cells in the blood of individual mice having transplantation with 200 Lin⁻c-kit⁺Sca-1⁺CD38⁻or 100 Lin⁻c-kit⁺Sca-1⁺CD38⁺marrow cells of normal mice 6 months before.

The numbers of transplanted CD38⁻ and CD38⁺cells reflect the 2:1 ratio of the cells in R2 and R3 windows of Figure1. Results shown are representative of 3 experiments.
