Assembloid - 3d mimetic tissue structure based on patient- derived multiple cell types and method of manufacturing the same

Abstract

The present invention relates to a 3 dimensional mimetic tissue structure—“Assembloid” based on patient-derived multiple cell types to develop next generation organoid technology serving as a novel platform for new drug development and a disease model and a method of manufacturing the same, and more particularly, to a stem cell- or tumor cell-based 3D multicellular mimetic tissue structure manufactured by reconstituting epithelial or tumor cells with various cellular components of a microenvironment such as stromal cells, vascular cells, immune cells or muscle cells based on three-dimensional (3D) bioprinting, and a method of manufacturing the same. As the stem cell- or tumor cell-based 3D multicellular mimetic tissue structure containing the major factors of a tissue microenvironment, such as stromal cells, vascular cells, immune cells and muscle cells, designed according to the present invention is confirmed to mimic physiological and pathological characteristics of tissue in the body better than conventional organoids, normal and tumor assembloids may be used as a new platform for new drug development and a disease model. More specifically, together with 3D bioprinting technology, it is expected that in vitro bladder tissue and bladder tumor tissue are effectively used as a platform to develop precise and personalized therapeutic options for bladder related diseases including bladder cancer.
