"Fig. 4. HE staining of mouse nasal mucosa in each group 400×
Notes: a: Normal+PBS group; b: AR+AMSC-exos group; c: AR+PBS group. The arrow in Fig. 3c indicates exfoliated cilia. The triangle and circle in Fig. 3c indicate eosinophil infiltration. PBS: Phosphate buffer saline; AR: Allergic rhinitis; AMSC-exos: adipose mesenchymal stem cell-derived exosomes."
"Fig. 5. PAS staining of mouse nasal mucosa in each group 400×
Notes: a: Normal+PBS group; b: AR+AMSC-exos group; c: AR+PBS group. Goblet cells are in the ellipse in Fig. 4c. The triangles in Fig. 4b indicate goblet cells. PBS: Phosphate buffer saline; AR: Allergic rhinitis; AMSC-exos: adipose mesenchymal stem cell-derived exosomes."
