Microscopic images of dendritic cells following cultivation with recombinant granulocyte macrophage colony-stimulating factor (GM-CSF) and recombinant interleukin-4 (IL-4). All of the images were taken at 200× magnification. a) Blood dendritic cells (B-DCs) collected after 3 days of incubation with recombinant proteins of GM-CSF and IL-4. Solid arrows show cells with extended dendrites, one of which possessed several nodes aligning (indicated by arrowhead). Some cells had short projections on the surface (indicated by hollow arrow). b) B-DCs collected after 7 days of incubation with recombinant GM-CSF and IL-4. The cells were veiled with pseudopods (indicated by solid arrow). c) Lung dendritic cells (L-DCs) after 5 days of incubation with GM-CSF and IL-4. Cells demonstrated visible pseudopods (indicated by solid arrow)
