Q. What are mesenchymal stem cells?
A. Mesenchymal stem cells (MSCs) are a type of tissue stem cell.
They are found in bone marrow, adipose tissue, cord blood, and dental pulp.
MSCs were thought to differentiate into mesoderm-derived tissues (bone, cartilage, fat, muscle, blood vessels, etc.) (1),but recent studies have reported that they can also differentiate into cells of ectoderm- and endoderm-derived tissues (nerve cells, liver cells, kidney cells, pancreatic cells, skin cells, etc.) (2)(3)(4)(5)(6) and have attracted attention in the field of regenerative medicine (2)(3)(4)(5)(6), and is attracting attention in the field of regenerative medicine.
