Elevated TSG-6-encoding mRNA expression and protein release in RHE infected by Trichophyton rubrum arthroconidia. RHEs were infected or not infected by T. rubrum arthroconidia and maintained in culture for 4 additional days. (a) PAS staining with α-amylase pretreatment and hemalun counterstaining and (b) HA detection. Bar = 20 μm. (c) TSG-6-encoding mRNA detection using in situ hybridization and hemalun counterstaining. Bar = 20 μm. (d) LL37 mRNA expression assessed by RT-qPCR. The reference gene is RPLP0 (mean ± SD; n = 3; one-way ANOVA; ∗∗P < 0.01 vs. day 0). HA, hyaluronan; PAS, periodic-acid schiff; RHE, reconstructed human epidermis.
