| Comments | Expression of bone sialoprotein, biglyan, decorrin, and osteopontin is suggestive of bone lineage cells. |
| Complete Growth Medium | The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.

PubMed: 14704791 The K7M2 wt cell line was derived by intra-osseous injection of the K7 murine osteosarcoma cell line to the proximal tibia of a BALB/c mouse. The resultant primary tumor spontaneously metastasized to the lungs. A pulmonary metastasis was removed from the lung and then surgically implanted to a paraosteal tibial muscle flap of a na?ve mouse. This cycle of implantation of pulmonary metastasis to paraosteal tibial muscle flap sites was repeated, resulting in the K7M2 primary tumor. This tumor was dissociated to a single cell suspension to create the K7M2 wt cell line |
