Disclosed are compositions of bone precursor cells and methods for their preparation and use. Bone precursor cells are cells which are not hematopoietic and which can differentiate into osteoblasts upon exposure to a bone growth factor and deposit calcium into the extracellular matrix. Such bone precursor cells are useful in the treatment of certain bone related disorders and diseases, such as osteoporosis, or in promoting fracture repair. In addition, methods of differentiating bone precursor cells into osteoblasts, and other diagnostic and even prognostic methods are provided. |
