["\nAbstract\n\nAim\nAdipose‐derived stem cells (ASCs) therapies are emerging as a promising approach to therapeutic angiogenesis. Therapeutic persistence and reduced primitive stem cell function following cell delivery remains a critical hurdle for the clinical translation of stem cells in current approaches.\n\n\nMethods\nCultured ASCs were derived from subcutaneous white adipose tissue isolated from mice fed a normal diet (ND). Unilateral hindlimb ischaemia model was induced in high‐fat diet (HFD)‐fed mice by femoral artery interruption, after which photoactivated and non‐light‐treated ASCs were injected into the tail vein of mice. Laser Doppler imaging was conducted to measure the blood flow reperfusion. Capillary density was measured in the ischaemic gastrocnemius muscle. mRNA levels of angiogenic factors were determined by reverse‐transcription polymerase chain reaction. Flow cytometry was used to determine the characterization of ASCs and endothelial progenitor cell (EPC). Human ASCs secretomes were analysed by liquid chromatography tandem mass spectrometry.\n\n\nResults\nOur study demonstrated that photoactivated ND‐ASCs prolonged functional blood flow perfusion and increased ASCs‐derived EPC and neovascularization 38 days after ligation, when compared with saline‐treated controls. Profiling analysis in ischaemic muscles showed upregulation of genes associated with pro‐angiogenic factors after injection of photoactivated ND‐ASCs when compared with the non‐light‐treated ASCs or saline treated HFD mice. Mass spectrometry revealed that light‐treated ASCs conditioned medium retained a more complete pro‐angiogenic activity with significant upregulation of angiogenesis related proteins.\n\n\nConclusion\nOur data demonstrates that photoactivated ND‐ASCs improve blood flow recovery and their injection may prove to be a useful strategy for the prevention and treatment of diabetic peripheral arterial disease.\n\n", "Acta Physiologica, Volume 230, Issue 1, September 2020.
