FIG. 6.
Immunofluorescence and confocal microscopy of IL-20R2 and IL-20R1 in HTM cells. Representative images of IL-20R2 (A–D) and IL-20R1 (E–H) localization in HTM cells stimulated for 24 h with vehicle control (A, E), IL-20 at 100 ng/mL (B, F), IL-19 (C, G), and IL-24 (D, H). DAPI was used to stain the nuclei (blue). Scale bar=20 μm.
