Skin is the largest organ in the body, with a variety of functions, such as thermoregulation, physical barriers, and sensory transmission, etc. Therefore, to restore the function after injury as soon as possible is particularly important. Mesenchymal stem cells (MSCs) are derived from mesoderm, and can differentiate into a variety of tissues, such as cartilaginous tissue, myoideum, and adipose tissue. Weak immunogenicity of MSCs make them become the ideal seed cells of tissue engineering. MSCs have a wide range of sources, including known sources of bone marrow, skin, placenta, and adipose tissue, etc. MSCs from different sources also have many different mechanisms in wound repair. This article reviews the recent researches on MSCs in the treatment of chronic wounds, so as to explore new ideas for the clinical treatment of chronic wounds.
