Abstract (original English)
This study investigated the proteomic characteristics and biological functions of hypoxic exosomes derived from hypoxia-preconditioned feline adipose-derived mesenchymal stem cells (ADMSCs), aiming to reveal the remodeling effect of hypoxic preconditioning on the protein composition of exosomes derived from feline ADMSCs and its potential applications. CoCl 2 was used to mimic a hypoxic environment for ADMSCs, and exosomes were isolated by differential ultracentrifugation. The physical properties of the exosomes were characterized by transmission electron microscopy, nanoparticle tracking analysis, and Western blotting. Proteomic analysis revealed that hypoxic preconditioning significantly altered the exosomal proteomic profile, identifying 120 differentially expressed proteins (116 upregulated and 4 downregulated). Bioinformatic analysis indicated significant enrichment of key pathways including the hypoxia-inducible factor-1 (HIF-1) signaling pathway, adenosine monophosphate-activated protein kinase (AMPK) signaling pathway, autophagy, and proteasome function. Gene ontology (GO) functional annotation demonstrated significant enrichment of biological processes such as metabolic processes, cell cycle regulation, and signal transduction in the hypoxia-preconditioned group. Kyoto encyclopedia of genes and genomes (KEGG) analysis further suggested potential biological functions th
