Abstract

To provide an investigative tool for the study of osteosarcoma (OSA) biology we have developed a syngeneic (balb/c) murine model of OSA, using cell lines derived from a spontaneously occurring murine OSA (Schmidt et al. Differentiation 1988; 39: 151-60). This model is characterized by orthotopic primary tumor growth, a period of minimal residual disease, spontaneous pulmonary metastasis, and clonally related variants (K7M2 and K12) that differ in pulmonary metastatic potential. Primary tumor and pulmonary metastasis histology was consistent with OSA in human patients. Expression of bone sialoprotein, biglyan, decorrin, and osteopontin was suggestive of bone lineage cells. The development and use of a more aggressive OSA cell line (K7M2) resulted in spontaneous metastasis to the lungs in over 90% of mice, whereas metastases were seen in only 33% of mice when a less aggressive OSA cell line (K12; Schmidt et al. Differentiation 1988; 39: 151-60) was used. Death from metastasis occurred at a median of 76 days using K7M2 whereas no median was achieved after 140 days using K12. Angiogenic potential, characterized by CD31 and factor VIII staining of primary tumors and pulmonary metastases, was greater in the K7M2 model compared to the K12 model. No significant differences in the in vitro or in vivo expression of angiogenesis associated genes (flt1, flt4, TIE1, TIE2, and VEGF) was found between K7M2 and K12. This well characterized and relevant model of OSA will be a valuable resource to improve our understanding of the biology and treatment of metastasis in OSA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
