Figure Lengend Snippet: ADSC Exo downregulate the expression of Smad2 by delivering miR-125b-5p. ( a ) Hotmap showing miRNA microarray results of ADSC Exo. ( b ) PCR results of the expression of 5 miRNAs (miR-125b-5p, miR-10a-5p, miR-23a-3p, miR-21-5p and miR-92a-3p) in ADSC Exo. ( c ) PCR results indicating miR-125b-5p expression in PBS- and ADSC Exo-treated HSFs, * * p < 0.01. ( d ) Structure and luciferase results of the dual luciferase reporter gene, * * p <0.01. ( e ) PCR results indicating miR-125b-5p expression in negative control (NC), miR-125b-5p expression mimic- and inhibitor-treated HSFs, * * p < 0.01. ( f ) Western blot results of α-SMA, COL1, COL3, p-Smad2 and Smad2 expression in NC, miR-125b-5p expression mimic- and inhibitor-treated HSFs. ADSC adipose-derived stem cells, Exo exosomes, PBS phosphate-buffered saline, H&E hematoxylin and eosin, HSFs hypertrophic scar fibroblasts
Article Snippet: The membrane was then blocked with 5% skim milk for 1 h at room temperature in TBST and probed with the following antibodies: COL1 (1 : 1000, Abcam, Cambridge, UK), COL3 (1 : 1000, Abcam, Cambridge, UK), α-SMA (1 : 1000, CST, USA), CD9, CD63 (1 : 1000, Proteintech, China), Smad2 antibody sampling kit (1 : 1000, CST) and β-actin (1 : 1000, Xi’an Johnson & Johnson) and incubated overnight at 4°C.
