|Keywords:||Human ovarian cancer; oestrogen receptor negative|
|Cell Line Description:||
PEO23 is an adherent cell line derived from a malignant effusion from the peritoneal ascites of a patient with a well differentiated serous adenocarcinoma. PEO23 was collected on relapse after cisplatin and chlorambucil treatment. PEO23 exhibits poor growth in semi-solid medium (agar). PEO23 is from the same patient as TO14 cell line (ECACC Catalogue number 10081203) and PEO14 (ECACC Catalogue number 10032311).
This cell line is one of nine from the PE ovarian adenocarcinoma panel (derived from 4 patients at varying stages of ovarian cancer, isolated from various malignant sites, and at various treatment stages) available at ECACC which provides a model system for research into the mechanism of oestrogen action on ovarian adenocarcinoma tumour cells, and for the study of efficacy and toxicity of oestrogen protagonists.>

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.
Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
