title: Orthotopic bone induction at sites of Moloney murine sarcoma virus inoculation in mice.
abstract: Moloney murine sarcoma virus (M-MSV) induces at the site of inoculation in newborn and adult mice and rats various types of sarcoma, including osteosarcoma. The induced tumours are fatal in newborn, whereas sarcomas developed in adult animals regress spontaneously. The regression is mediated mainly by a cellular response. We have now demonstrated that the presence of sarcomas induced by M-MSV is a powerful stimulus for periosteal osteogenesis around tumour masses. Orthotopically induced osteogenesis by M-MSV may serve as a model for local regulation of bone growth and for cell differentiation studies, and may help explain the aetiology of some human bone disorders.
