Morphology and immunostaining of IL-4 DC and IL-10 DC. Rat BMDC were isolated from cell clusters on day 6 of culture (A). Cells prepared on cytospin slides stained positive for monoclonal antibodies Ox62 (rat DC marker) (B), Ox6 (MHC class II) (C), and CD68 (D). Shown are representative IL-4 DC results, which are similar to those for IL-10 DC. Magnification: ×200 (A, C, D) and ×400 (B).
