Fluorescent cell distribution (× 50) in nasal mucosa tissue sections obtained from mice on days 3, 7, 14, and 21 after transplantation of GFP-labeled hUCMSCs. (A–C) were obtained on the 3rd day, (D–F) were obtained on the 7th day, (G–I) were obtained on the 14th day, and (J–L) were obtained on the 21st day. (A), (D), (G), and (J) show the results of the nasal drip group; (B), (E), (H), and (K) show the results of the intraperitoneal injection group; (C), (F), (I), and (L) show the results of the tail vein injection group.
