Mesenchymal stem cell therapies for bone and tendon conditions

Bone, tendon, and cartilage are highly specialized musculoskeletal connective tissues that are subject to injury and degeneration. These tissues have relatively poor healing capabilities, and coupled with their variable response to established medical treatments, produce significant morbidity. Mesenchymal stem cells (MSCs) are capable of regenerating skeletal tissues and therefore offer great promise in the treatment of connective tissue pathologies. Adult MSCs are multipotent cells that possess the properties of proliferation and differentiation into all connective tissues. Furthermore, they can be gene modified to secrete growth factors and utilized in connective tissue engineering. Potential MSC-based therapies for bone and tendon conditions are reviewed in this chapter.
