“…They can differentiate not only into mesoderm, but can also differentiate into endoderm and neuroectoderm-derived cells, and can be targeted to differentiate into various terminal functional cells, such as muscle cells, osteocyte, vascular cells, endothelial cells, and nerve cells, under specific conditions ( Galipeau and Sensebe, 2018 ). MSCs have obtained increasing attention as seed cells for tissue engineering ( Gao et al, 2021 ; Rajasingh et al, 2021 ). In addition, MSCs can also promote the repair of various tissue injuries through direct intercellular contact and paracrine factors such as cytokines, growth factors, and small extracellular vesicles (sEV) ( Keshtkar et al, 2018 ; Xia et al, 2019 ).…”
