CD1a⁺ cells are dendritic cells.

(A) Cytospin preparations from lymphoid cultures showing small B-lymphoid cells with scanty cytoplasm and large cells with typical dendritic morphology. (B) FACS analysis of large cells generated in lymphoid culture (gated using FSC as in Figure 3H). CD1a⁺cells uniformly express high levels of HLA-DR but do not express the monocyte marker CD14. Wright-Giemsa stain, original magnification × 40.
