Article Abstract

We present a protocol to generate immunocompetent 3D tumor-on-chip models from human solid tumors, enabling more accurate therapy response assessment than traditional 2D assays. We outline the isolation and culture of autologous tumor cells, CD8 tumor-infiltrating lymphocytes, and cancer-associated fibroblasts, followed by their encapsulation in a 3D biomimetic matrix within microfluidic devices and subsequent video microscopy. The protocol is adaptable to other tumor types, including breast and colon cancer. For complete details on the use and execution of this protocol, please refer to Veith et al..

The endothelium compartment is a key player in tumor initiation and progression, but most existing tumor-on-chip models lack clinical relevance. Here, a 3D vascularized tumor-on-chip (vToC) model, generated with patient-derived microvascular endothelial cells (ECs) that are freshly isolated from surgical lung cancer samples, is presented. The microvessel molecular identity, morphology, and functionality are assessed by transcriptomic, immunofluorescence, TNF-α stimulation, and permeability assays.

The advances in cancer immunotherapy come with several obstacles, limiting its widespread use and benefits so far only to a small subset of patients. One of the underlying challenges remains to be the lack of representative nonclinical models that translate to human immunity and are able to predict clinical efficacy and safety outcomes. In recent years, immunocompetent Cancer-on-Chip models emerge as an alternative human-based platform that enables the integration and manipulation of complex tumor microenvironment.

A major challenge in cancer research is the complexity of the tumor microenvironment, which includes the host immunological setting. Inspired by the emerging technology of organ-on-chip, we achieved 3D co-cultures in microfluidic devices (integrating four cell populations: cancer, immune, endothelial, and fibroblasts) to reconstitute ex vivo a human tumor ecosystem (HER2 breast cancer). We visualized and quantified the complex dynamics of this tumor-on-chip, in the absence or in the presence of the drug trastuzumab (Herceptin), a targeted antibody therapy directed against the HER2 receptor.
