Fig. 1. Morphological observation of bone marrow-derived dendritic cells (BMDCs) during the differentiation procedures. The pictures were captured by inverted microscope equipped with a digital imaging system (Leica DMi1; Leica Microsystems, Germany). (A) BMDCs observed at day 2 of culture. (B) Morphology of the non-stimulated BMDCs (arrows) at day 7 of culture. (C) Morphology of DCs (arrows) pulsed with lipopolysaccharide at day 9 of culture. (D) Morphology of DCs (arrows) stimulated with Salmonella Typhi ghost at day 9 of culture. Scale bars = 50 µm (A–D).
