Welcome to the web site for the Children's Oncology Group (COG) Cell Culture and Xenograft Repository. This repository distributes well characterized and validated cell lines and mouse xenografts established from childhood cancers to investigators seeking to do research on childhood cancer.

Cell cultures, continuous cell lines, and cryopreserved xenografts stored in the repository will be distributed to investigators free of charge. Payment of shipping by providing a Federal Express (or similar) account number is requested for US shipments and required for international shipments.

The COG Cell Line & Xenograft Repository is supported in part by a grant from the Cancer Prevention & Research Institute of Texas and by a generous grant from Alex's Lemonade Stand Foundation.
