ADSCs are a type of mesenchymal stem cells found in adipose tissue, with the potential to differentiate into various tissues. They offer advantages such as abundant quantity, easy accessibility, stable function, and low immune rejection. Two main methods for tissue repair and regeneration using ADSCs include implanting ADSCs-scaffold composites and utilizing ADSC-exos or ADSC-CM to release bioactive substances. The tissue regeneration potential and differentiation of ADSCs are regulated by various factors, and further research is needed to fully understand the mechanisms.
ADSCs are a large number of mesenchymal stem cells in Adipose tissue, which can be applied to tissue engineering. ADSCs have the potential of multi-directional differentiation, and can differentiate into bone tissue, cardiac tissue, urothelial cells, skin tissue, etc. Compared with other mesenchymal stem cells, ADSCs have a multitude of promising advantages, such as abundant number, accessibility in cell culture, stable function, and less immune rejection. There are two main methods to use ADSCs for tissue repair and regeneration. One is to implant the ADSCs-scaffold composite into the injured site to promote tissue regeneration. The other is cell-free therapy: using ADSC-exos or ADSC-CM alone to release a large number of miRNAs, cytokines and other bioactive substances to promote tissue regeneration. The tissue regeneration potential of ADSCs is regulated by a variety of cytokines, signaling molecules, and external environment. The differentiation of ADSCs into different tissues is also induced by growth factors, ions, hormones, scaffold materials, physical stimulation, and other factors. The specific mechanisms are complex, and most of the signaling pathways need to be further explored. This article reviews and summarizes the mechanism and clinical application of ADSCs in tissue injury repair so far, and puts forward further problems that need to be solved in this field, hoping to provide directions for further research in this field.(c) 2023, The Japanese Society for Regenerative Medicine.
