The Core Facility for Organoids provides services in the establishment and cultivation of organoids, as well as the testing of clinically relevant substances on these cultures. Organoids are three-dimensional epithelial structures that mimic the structure and function of the organ or tissue from which they are derived.
So far, the cultivation conditions for organoids based on tumor material of pancreatic cancer and colorectal cancer have been established in the Core Facility. Organoid cultures for further tumor types such as breast cancer and urothelial carcinoma are currently being established.

Project registration



Starting from small tumor pieces, patient-specific organoid cultures can be established, which can be passaged in vitro due to their self-renewal and self-organization ability (Fig.1).

For this purpose, a special matrix (e.g. Matrigel) and media with appropriate niche factors are used (Fig.2).  These "patient avatars" reflect the structural and molecular characteristics of the original tumor tissue and can be used, among other things, to investigate the response to substances used in cancer therapy, such as chemotherapeutic agents or small-molecule inhibitors.

A correlation between clinical response in patients and results from organoid assays has already been described for various tumor types [s. Publications].
