Mesenchymal stem cells(MSCs)are pluripotent stem cells isolated from various tissues,but mostly from bone marrow,adipose tissue,and umbilical cord blood.Well known for their mesenchymal lineages differentiation(e.g.,bone,cartilage and fat tissues),it was suggested that MSCs possess plasticity properties enabling them to differentiate into non-mesenchymal lineages.Indeed,several protocols claimed for
