Mesenchymal Stem Cells (MSCs): Characteristics, Sources, and Research Applications

Mesenchymal Stem Cells (MSCs) are among the most extensively studied adult stem cell populations in biomedical research. Their capacity for self-renewal, multilineage differentiation, and immunomodulatory activity has made them one of the most widely used cell models in regenerative medicine, tissue engineering, disease modeling, and drug discovery. Due to their accessibility, expansion capability, and diverse biological functions, MSCs have become an essential tool for both basic research and preclinical studies.

Biological Characteristics of Mesenchymal Stem Cells

MSCs exhibit unique biological properties that support their broad applications in scientific research. Under appropriate in vitro culture conditions, MSCs can differentiate into osteoblasts, adipocytes, and chondroblasts, representing their trilineage differentiation potential.

Beyond differentiation capacity, MSCs play important roles in regulating tissue repair and immune responses. They secrete a variety of cytokines, growth factors, chemokines, and extracellular vesicles that contribute to tissue regeneration and immune regulation primarily through paracrine mechanisms.

According to the International Society for Cell & Gene Therapy (ISCT), cultured MSCs should express specific positive surface markers, including CD73, CD90, and CD105, while lacking the expression of hematopoietic and immune cell markers such as CD34, CD45, CD14/CD11b, CD79α/CD19, and HLA-DR. These characteristics are widely used for MSC identification and quality evaluation.

Selecting the Right MSC Source for Research

MSCs can be isolated from various human tissues, and different sources exhibit distinct biological characteristics that may influence experimental outcomes.

Choosing an appropriate MSC source according to research objectives is essential for improving experimental consistency and obtaining meaningful results.
