Frequency of Tumor Development Following i.p. Injection of Tumor Cell Aggregates Derived from Ovarian Cancer Patient Solid Tumors.

aEach experiment was conducted with tumor tissue derived from a different ovarian cancer patient. In experiment 5A and B the cell aggregates was generated from the same tumor.bMice were injected i.p. with tumor-derived cell aggregates obtained from five different ovarian cancer patients, that is generated as indicated in Materials and Methods section.cEvidence of tumor was established by the presence of grossly detected tumor nodules in the peritoneal cavity, histological evidence of tumor in the organs or both. In each experiment, #1–4, one of the 10 mice died without evaluation. In experiment #5 one of the mice was sacrificed at day 85 post inoculation without any evidence of gross tumor. In experiment 5B – one of the mice died without evaluation.
