Kinetics of CD14 expression on UCB-derived populations.

(A) CD14 expression in total UCB/ACF (■), UCB/CD14⁺(▨), UCB/CD34⁺ (░), and UCB/CD56⁺ (▪) populations and (B) CD14 expression on the CD56⁺ cells derived from these populations. The percentages in panel B have been obtained by gating on CD56⁺ cells. (C) Dot plots of UCB/CD14⁺ cells after 5 days and (D) of UCB/CD34⁺ cells after 15 days of culture in the presence of FL and IL-15. Gating on CD56⁺ cells. Of the 3 experiments conducted, 1 representative example is shown.
