abstract: Characterized cell lines are absolutely necessary in applied research of cell biology and medicine. For the completion of diagnosis and therapy especially in pediatric oncology we are establishing a Cell Bank for Pediatric Tumors. The Cell Bank for Pediatric Tumors collects tissue samples of different types of solid malignant tumors from children and young adults. The specimens are transferred to in vitro culture (guidelines of the American Type Culture Collection-ATCC), the resulting cells are characterized to assure accordance with the histogenesis of the original tumor and stored in liquid nitrogen. The cell cultures are characterized morphologically (phase contrast microscopy) and immunocytochemically (ABC-method). To prove the malignancy of cells in primary culture the amount of hypertetraploid cells was determined (DNA-Scanning-Cytophotometry). Cell lines are checked to find out whether they develop tumors in nude mice followed by an analysis of the karyotype. Additional investigations (e.g. in vitro test of cytostatic drug resistance) are carried out on request by the sender. Part of the tumor tissue which is used to start the cell culture is in parallel diagnosed histopathologically at the Children's Tumor Register, Kiel and/or at the Charité. By the end of the year 1995 the Cell Bank for Pediatric Tumors had received 183 different specimens including 123 solid tumors (e.g. 24 neuroblastomas, 18 osteosarcomas, 12 Wilms' tumors, 13 rhabdomyosarcomas), 44 tissue specimens without any malignant cells, 8 probes without vital cells and 8 leukemias and lymphomas. We were able to establish primary cell cultures of 50% of the sterile tumor tissue probes, to cultivate them for a minimum of 5-10 passages, to characterize and freeze them. Six out of these tumor cell lines were already cultivated for one year and are available to the scientific community.
