Stem cells have special properties, such as self-renewal, proliferation, and the multilineage differentiation. Generally, stem cells are categorized into embryonic stem cells (ESCs), adult stem cells (ASCs), and induced pluripotent stem cells (iPSCs). Mesenchymal stem cells (MSCs) are a type of ASCs with a multipotent property. MSCs are easily isolated from various tissues and organs in the human body and can differentiation into multiple lineages, such as bone, cartilage, fat, and muscles. Compared to ESCs and iPSCs, MSCs possess less proliferation and differentiation capacities, therefore, a much scientific concern is concerned toward promoting the proliferation and the differentiation potency of MSCs. There are various methods to achieve this goal such as the treatment of various types of small molecules or culturing on specific peptides. Producing of high-quality MSCs with enhanced proliferation and differentiation capacities will definitely be a useful tool for stem cell-mediated tissue regeneration and the further clinical application.
