Detection of insulin-FITC after intranasal delivery. a Experimental scheme. b Representative images of hippocampal tissues without and with insulin-FITC in Ctrl mice (n = 3 per group). Anterior-posterior coordinates of images according to mouse brain atlas are Bregma − 1.90 mm (− Insulin-FITC) and − 2.14 mm (+ Insulin-FITC) respectively. Scale bar, 50 μm. c Representative images of hippocampal tissues without and with insulin-FITC in CRS mice (n = 3 per group). Anterior-posterior coordinates of images according to mouse brain atlas are Bregma − 1.96 mm (− Insulin-FITC) and − 2.26 mm (+ Insulin-FITC) respectively. Scale bar, 50 μm
