MiRNA sequencing analysis. A Heat map of miRNA sequencing (miRNA-seq) analysis of rat tendons treated with or without HUMSC-Exos (red: high expression, green: low expression, A1–A3 sham group, B1–B3 HUMSC-Exo group (n = 3 per group), and red arrow: rno-miR-29a-3p. B, C, D The expression of hsa-miR-29a-3p and rno-miR-29a-3p determined by Q-RT-PCR (n = 5 per group). ***P < 0.001. E KEGG analysis chart of miRNA-seq. F Representative western blot image of p-mTOR and mTOR
