Organ-Chip Application


Advance the development of novel immunotherapies and better understand the tumor microenvironment


Anti-cancer drug candidates are becoming more difficult to model due to the increase in human-specific cancer therapies

Despite decades of research, there remains a lack of effective and safe treatments for many forms of cancer, partially due to a lack of human-relevant models of cancer progression. Although animal models can effectively model some human cancer behaviors, they do not allow researchers to study the impact of specific tissue components, investigate the role of the tumor microenvironment (TME), or visualize how cancer cells behave over time when interacting with stromal and immune cells. Meanwhile, conventional in vitro models fail to reproduce the complexity that influences cancer behavior in vivo, and cannot appropriately model more recent advancements in cancer therapeutics.

How we can help

Model human-specific cancer therapies with Organ-on-a-Chip technology

Organ-on-a-Chip technology allows researchers to recreate the human tumor microenvironment in vitro, enabling mechanistic studies of cancer cell behavior and drug efficacy and safety. Endothelial co-culture provides important cell-cell interactions, while media flow and tissue-relevant stretch help model the mechanical forces cancer cells experience in the body. With these highly-tunable models, it is possible to modulate various cellular, molecular, chemical, and biophysical properties in a controlled manner to investigate their impact on cancer progression and behavior. The improved gene expression demonstrated in Organ-Chips also enables the evaluation of immuno-oncology therapeutic safety risk, not possible with conventional cell culture.


Complex 3D in vitro models supporting novel interrogation of cancer progression

Cancer progression is a complex process that is not fully understood due to the limited ability of animal and in vitro models to recapitulate the human tumor microenvironment. With Organ-Chips, researchers can model early stages of cancer metastasis and intravasation of tumor cells into the vasculature. By modeling and tuning the tumor microenvironment (TME), including peristaltic-like stretch, media flow, and tumor-stromal tumor-endothelial interactions, researchers can better understand—and ultimately control—aspects of cancer progression.


Model the entire journey of CAR T-cell therapy for solid tumors, from vascular administration to target cell killing

With the CAR T workflow for Emulate Organ-Chips, researchers can model the entire journey of CAR T-cell therapy from blood vessel to target—including CAR T cell vascular administration, tumor inflammation-specific endothelial cell attachment and migration, and antigen-specific killing—in a vascularized cancer cell line model.

T-Cell Engagement and Activation

An emerging new standard for immunotherapeutic safety testing and optimization

Although promising for immunotherapy, T-cell bispecific antibodies (TCBs) present an on-target, off-tumor safety risk due to low levels of expression of tumor antigens in healthy tissues. Increasingly, TCBs target human-specific antigens not expressed in animal models, rendering them uninformative for preclinical studies. Even conventional human cell-based models fail to replicate in vivo gene expression, limiting their value. Because Organ-Chips incorporate human cells, cell-cell interactions, and mechanical forces, gene expression is much closer to in vivo, enabling a more human-relevant and clinically translatable assessment of TCB safety and efficacy.

How Organ-Chips are being used

In a recent collaboration, Emulate and Roche scientists evaluated the safety of a TCB candidate targeting carcinoembryonic antigen (CEA), a cell surface antigen expressed in varying amounts in the intestine and often overexpressed in colorectal cancer.

By administering the TCB directly to the epithelial channel of the Duodenum Intestine-Chip or Colon Intestine-Chip, scientists were able to identify the potential on-target, off-tumor safety risk posed to healthy human colon tissue.

Data gathered using both chips demonstrated regional and target affinity-dependent gastrointestinal toxicity in response to TCB treatment, recreating in vivo mechanisms of TCB-mediated toxicity. These effects were not seen in conventional cell culture and enabled Roche to identify a safer TCB candidate by determining a safe therapeutic window.
