Culture and identification of dendritic cells. A, Morphological observation of dendritic cells cultured in vitro for 8 days. a, Non-infected DCs (×400). b, Infected with UV-Tianjin (MOI = 200) for 48 h (×400). Black arrows indicate mature DCs with many dendritic protrusions. B, Flow cytometric analysis of the expressing of CD11c molecule specific for DCs cultured in vitro for 6 days. Results are representative of three independent experiments.
