Peripheral T cells after injection of CD34⁺CD3⁻ UCB cells.

(A, B) Expression of CD34 and CD3 before (CD34⁺-enriched UCB cells) and after cell sorting, respectively, is shown. Presence of human CD3⁺ T cells in murine thymus (C) and spleen (D) 12 weeks after injection of CD34⁺CD3⁻ cells is shown. Plots are gated on human CD45⁺ cells.
