Mouse iris with dendritic cells tagged by fluorescent antigen.

A top view (x,y @ z) of mouse iris, where dendritic cells have been tagged with fluorescent antigen (ovalbumin-Green). The gray scale is the reflectance-mode confocal image created with the blue argon laser, which indicates the non-fluorescent structures. The green color is the fluorescence-mode confocal image showing tagged dendritic cells. The movie scans down through increasing depth z.
