1.1. Definition

MSCs are multipotent stromal cells that can differentiate into a variety of cell types, including: osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue). MSCs exist in organisms (in-vivo) and have been studied as well in tissue culture (in-vitro) [2].
