A 3D decellularized bone scaffold seeded with cancer cells, such as prostate cancer cells or Ewing's sarcoma is provided. The three-dimensional includes Ewing's sarcoma (ES) tumor cells; and an engineered human bone scaffold. The engineered human bone scaffold further includes osteoblasts that secrete substance of the human bone, and osteoclasts that absorb bone tissue during growth and healing. The engineered human bone scaffold includes the tissue engineered three-dimensional model which recapitulates the osteolytic process. The engineered human bone scaffold is engineered by co-culturing of osteoblasts and osteoclasts. The osteoblast is produced by cell differentiation process from mesenchymal stem cells. The osteoclast is produced by cell differentiation from human monocytes, wherein the human monocytes are isolated from buffy coats. The scaffold can be used with cancer cell lines to identify therapeutic targets to slow, stop, and reverse tumor growth and progression as well as to predict the efficacy of potential therapeutics.
