Expression of CD1a, CD14, and accessory molecules on 14-day cultured CD34⁺ cells. After 14 days of CD34⁺ cell culture with GM-CSF, TNF-α, IL-4, and SCF, cells were obtained and double-stained with FITC- or PE- anti-CD1a and HLA-DR, CD80, CD86, CD40, and CD83 MoAbs. Irrelevant mouse Igs were used as a negative control.
