The morphology of DCs in different groups on the 7th day (× 400). A. IFN-λ1 group: No morphological changes of the adherent cells were observed. These cells from IFN-λ1 group were mostly suspended, but there was no change in cell volume. B. Routine group: The shape of the cells changed: the adherent cells gradually became suspended and increased in volume, then adherent cell stretching was seen and cell clusters formed in the surface of the cells after five days of culture. C. Combination group: dendrite crossed on the surface of cells that formed the typical DC morphology.
