abstract：:Previously we have reported the development of a model in vitro system for the study of osteosarcoma. In this system, when chick periosteal explants are infected with Fujinami sarcoma virus (FSV), osteosarcoma-like tissue is formed. In the present study, a series of histopathologic parameters of neoplastic transformat...
