“…Although most studies were conducted with bone marrow derived mesenchymal progenitor cells (MPCs), other tissues have been described to contain osteoprogenitor cells with similar regenerative potential including adipose tissue, muscle, umbilical cord blood, periosteum, dental pulp and periodontal ligament [4,[39][40][41][42][43][44][45]. The multilineage differentiation ability, paracrine effects and immunomodulatory properties of MPCs make them an ideal for tissue engineering and regenerative purposes [5,7,[46][47][48]. Under appropriate conditions MPCs could be differentiated into a variety of mesenchymal tissues such as bone, cartilage, tendon, ligament, marrow stroma, muscle, fat and dermis [4,[49][50][51][52][53].…”
