A Study to Establish a Living Breast Organoid Biobank for Translational Research


About this study

Researchers at Mayo Clinic are developing a Biobank of adult stem cell-rich breast organoids, a new research resource to facilitate normal and cancer stem cell research. Subjects in the Biobank will provide samples of excess breast tissue, complete a health questionnaire, and allow access to medical records now and in the future. The Biobank serves as a library for researchers; instead of having to look for volunteers for each new project, researchers can use samples from the Biobank as well as share information already collected.
