Salmon MPs develop dendritic morphology following prolonged treatment with CpGs. (A) Images of non-stimulated MPs and cells stimulated for 7 days with 2 μM CpGs and 20 μg/ml of polyI:C. The arrow indicates a typical DC-like cell observed in the CpG-treated samples. (B) Dynamic reorganization of the morphology of CpG-treated MPs. Cells were stimulated as in panel A and images were taken at 30min intervals over a period of 90min. The arrow points at elongated DC-like cell which changes morphology into a more rounded macrophage-like cell. The arrowhead indicates a cell which undergoes the opposite changes. Images were taken at X200 magnification.
