Growing human sarcomas in culture.
Efforts to establish human soft tissue and bone sarcomas in long-term cultures are described. Of 49 attempts 22 (45%) were successful, yielding cells that proliferated in vitro for 6 months or longer. Infrequent medium changes, maintenance of pH in physiologic range and avoidance of early trypsinization all appear to be important for survival of explanted cells and their initial growth under culture conditions. Cytologic criteria can be used to confirm that cells in established lines derive from malignant mesenchymal cells present in the tumors of origin.
