The densities of feline epidermal dendritic cells expressing CD18, MHC class II and CD1a antigens were determined for four anatomical locations in 19 cats of European breed in blind conditions. The densities (±SD) of CD1a+ Langerhans cells in the skin of the abdominal wall (269 ± 68 cells/mm2), the back (363 ± 19), the internal side of the ear (572 ± 30) and the external side of the ear (502 ± 32) were significantly different, with young and old animals displaying less stained cells than adults. No significant differences in the mean densities were found with regard to sex, colour or antibody used.
