Mesenchymal Stem Cells (MSCs) are a type of stem cells that are multipotent, meaning they have the potential to differentiate into multiple cell types. These include osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells), and adipocytes (fat cells). MSCs are primarily found in the bone marrow, but they can also be isolated from other tissues like adipose tissue, umbilical cord blood, and even dental pulp.
