neoplasm
• ex vivo, osteosarcoma-derived cell lines exhibit increased proliferation in BrdU incorporation assays, a higher abundance of tyrosine-phosphorylated proteins, and no cellular growth in response to long-term administration of Mdk (midkine, a heparin-binding growth factor known to antagonize Ptprz1 in other cell types)
• at 52 weeks of age, 7 of 38 (~19%) mice exhibit osteosarcoma development by contact X-ray analysis
• skeletal tumors are found in three different locations i.e., ribs, spine or long bones, but not in craniofacial bones, and consist of mineralized tissue
• undecalcified histology showed that tumors represent bony tissue with osteocytes embedded into mineralized matrix, confirming their osteosarcoma nature
• cell lines derived from tumors and cultured in the presence of ascorbic acid and beta-glycerophosphate are able to form a mineralized matrix and show differential expression of osteoblast differentiation markers
