Mesenchymal stem cells are present in many human tissues and serve as a readily available source of undifferentiated cells being capable to form specific tissues like bone, cartilage, fat, muscle and tendon. They represent an attractive and promising field in tissue regeneration and engineering for treatment applications in a wide range of trauma and orthopaedic conditions. The bone marrow serves as a reservoir for different classes of stem cells. In addition to haemopoietic stem cells, the bone marrow capacity.comprises a population of marrow stromal cells or mesenchymal stem cells (MSCs). These cells exhibit multilineage differentiation
