Abstract (original English)

Aim: The effects of MALAT1 from human adipose-derived stem cell (ADSC) exosomes in skin wound healing were investigated. Material & methods: The viability, apoptosis and migration ability of human skin fibroblasts (HSFs) were evaluated by Cell Counting Kit-8 assay, flow cytometry and scratch assay, respectively. A mouse model was established to evaluate the role of exosomal MALAT1 in skin wound healing in vivo . Results: Human ADSC exosomes promoted the proliferation and migration of HSFs and increased MALAT1 expression. MALAT1 silencing in human ADSCs inhibited HSF viability and migration, promoted HSF apoptosis and inhibited angiogenesis by upregulating miR-378a. Overexpression of miR-378a inhibited the migration and proliferation of HSFs by downregulating FGF2 expression. ADSC exosomes promoted skin wound healing by mediating MALAT1 in vivo . Conclusion: Exosomal MALAT1 accelerated skin wound healing by regulating the miR-378a/FGF2 axis, suggesting that MALAT1 might be used as a potential target for cutaneous wound treatment. Skin wound healing is a process of synergistic action of multiple factors. Adipose-derived stem cells (ADSCs), a group of stem cells, are recruited into damaged tissues and secret several cytokines, which promote nascent tissue formation. ADSC-derived exosomes play crucial roles in wound healing as a paracrine vehicle for delivering chemokines, growth f
