Mesenchymal stem cells (MSCs) are adult, nonhematopoietic, stem cells that were initially isolated from bone marrow. Now they can be isolated from almost every tissue of the body. They have the ability to self-renew and differentiate into multiple cell lineage, including bone, chondrocytes, adipocytes, tenocytes and cardiomyocytes, and it makes them an attractive cell source for a new generation of cell-based regenerative therapies. In this review we try to summarize data on sources and the biological properties of MSCs.
Keywords: bone marrow; mesenchymal stem cells; stromal cells; tissue engineering.
