Monoclonal antibodies (MAb) are provided which have binding specificity to an antigen expressed on osteogenic and fibroblastic cells (OFA) and are capable of binding to osteogenic and fibroblastic cells at a substantially higher extent as compared to their binding to skin fibroblasts and stromal adipocytes. Also provided is a novel osteogenic and fibroblastic antigen (OFA) which is expressed on osteogenic and fibroblastic cells at a higher level than its expression in skin fibroblasts and stromal adipocytes having a molecular weight of about 80 kD as determined by western blotting or immunoprecipitation. The OFA and anti-OFA-MAbs are useful in the diagnosis and treatment of various hone related conditions.
