Summary
A method is described to create organoids using patient-derived xenografts (PDX) for in vitro screening, resulting in matched pairs of in vivo/in vitro models. PDX tumors were harvested/processed into small pieces mechanically or enzymatically, followed by the Clevers’ method to grow tumor organoids that were passaged, cryopreserved and characterized against the original PDX.
