(a): Whole skin explants from BALB/c mice were incubated for 30′ to 48h in culture medium containing NLDC145 (anti-mouse DEC-205) hybridoma supernatant. Epidermis was then separated from dermis, fixed, and targeting mAb was revealed with anti-rat IgG secondary Ab. Arrowheads indicate dermal cells targeted in situ. Arrows point at DC-filled dermal lymphatic vessels. (b): Whole skin explants from BALB/c mice were incubated for 18 h in culture medium containing NLDC145 or LODNP16 (isotype control) hybridoma supernatants, then epidermis was separated, fixed, and stained with anti-rat IgG Ab. (c): Whole skin explants from BALB/c or C57BL/6 mice were incubated for 4h with 5μg/mL of the indicated purified mAb, then epidermis was separated, fixed, and stained with anti-rat IgG Ab. Scale bars = 100μm. Results are representative of three independent experiments.
