Figure Lengend Snippet: The expression/activity of EPCR, PC/aPC, PAR1, and PAR2 in the skin of normal and CHS mice. ( A ) Representative images of EPCR, PC/aPC, PAR1, and PAR2 expression in skin tissues of WT and EPCRKO mice (8 weeks old, flank skin), detected by immunochemistry. ( B ) Representative images of EPCR, PC/aPC, PAR1, and PAR2 expression in ear tissues of WT and EPCRKO mice with CHS at day 14. ( C ) Representative images of EPCR, PC/aPC, PAR1, and PAR2 expression in skin tissues of WT mice treated with 3K3A-aPC (1 mg/kg). Scale bars in ( A – C ): 100 µm. ( D ) The staining intensity of EPCR, PC/aPC, PAR1, and PAR2 in the skin epidermis in ( A – C ), expressed as means ± SD (n = 8). ( E ) aPC activity in the ear skin tissues/plasma, expressed as means ± SD (n = 8 for all groups), against human recombinant aPC. * p < 0.05. ** p < 0.01.
Article Snippet: Mouse skin tissue sections were de-paraffinized, heat-retrieved, and immunostained using rabbit anti-mouse PAR1 and goat anti-mouse PAR2 antibodies (Santa Cruz Biotech, Dallas, TX, USA), goat anti-mouse EPCR and rabbit anti-mouse PC/aPC antibodies (R&D Systems).
