Abstract: The present disclosure describes a high-throughput methodology for rapid and highly personalized screenings to identify efficacious anti-tumor immunotherapy regiments. In one embodiment, therapeutic agents or a combination thereof are screened by co-culturing tumor shaped organoid extrudates with a population of immune cells taken from the same patient. Reduced tumor cell functions or increased immune cell functions in the presence of the therapeutic agents or combination thereof would identify the therapeutic agents or combination thereof for treating the tumor in the patient.

Abstract: In one embodiment, the present disclosure provides a tissue culture well insert for use with a multi-wells tissue culture plate. The cylindrical well insert is configured to be inserted into the tissue culture wells, wherein the well insert comprises a carrier or platform section on which liver cells or other cells are deposited, and the carrier or platform section is positioned in the tissue culture wells so as to be suspended off the bottom of the tissue culture wells. The well insert is useful for co-culturing multiple cell types to create in vitro biological systems. One specific application is high-throughput anti-tumor drug screening in which the liver cells or other cells carried by the carrier or platform section of the insert are co-cultured with tumor organoids deposited or bioprinted to the bottom of the tissue culture well.
