B- and T-lineage potentials of CD34⁺CD81⁺ cells.

(A) Flow cytometric profile shows expression of CD19 and CD10 on lymphocyte-gated cells derived from 3 × 10³CD34⁺CD81⁺ cells cocultured with MS-5 cells for 4 weeks. (B) Flow cytometric profile shows expression of CD3 and CD4 on lymphocyte-gated cells derived from 5 × 10³CD34⁺CD81⁺ cells recovered in FTOC for 4 weeks.
