Recapitulate human vaccine and adjuvant responses

Model Overview

In vivo-like lymph node functionality

The Lymphoid Organ-Chip model supports the formation of lymphoid follicles with functional germinal centers similar to those found in secondary and tertiary lymphoid organs in vivo, enabling researchers to recapitulate human vaccine and adjuvant responses.

Benefits

3D Follicle Formation

Dynamic flow on-chip stimulates the assembly of large 3D multicellular aggregates.

Antigen-Specific Antibody Generation

Lymphoid Organ-Chips demonstrate significant anti-HA antibody generation following treatment with inactivated H5N1 virus.

Clinically Relevant Cytokine Production

The Lymphoid Organ-Chip displays clinically relevant levels of cytokines that are important for T cell expansion, survival, and helper functions.

Captures Donor-to-Donor Variability

Eight different human donors all produced anti-HA antibodies at detectable levels, with subsets of high and low responders identified.

Assess Responses to mRNA Vaccines

Myeloid cells capture and express mRNA vectored by lipid nanoparticles, enabling assessment of mRNA vaccines.

Neutralizing Antibody Production

Neutralizing antibody production against the SARS-CoV-2 spike protein has shown to be achieved after a culture duration of just six days.

The Lymphoid Organ-Chip design consists of a high-density 3D human PBMC culture within an ECM gel in the lower channel, while media and antigens are flowed in the upper channel of the chip.

The Lymphoid Organ-Chip is a Guided Model that Emulate has firsthand experience developing and supporting. It can be created using a Basic Research Kit and a user’s own cell sources. For Guided Models, Emulate offers guidelines and field scientist support to build a Lymphoid Organ-Chip using the Human Emulation System.

Case Studies

Community Publication

Ectopic Lymphoid Follicle Formation and Human Seasonal Influenza Vaccination Responses Recapitulated in an Organ-on-a-Chip

Read this publication to learn how researchers at the Wyss Institute developed a human model of ectopic lymphoid follicle formation, offering a new tool for studying lymphoid follicle development and a promising alternative to non-human primates for preclinical vaccine evaluation.

Clinically Relevant Cytokine Production

Lymphoid Organ-Chips show clinically relevant changes in cytokines 3 days after vaccination (C1-5) compared to unvaccinated chips. Changes observed in chips were similar to changes observed in the peripheral blood of 7 individuals (V1, 3, 4, 10–13) 1 day after vaccination as compared to their levels pre-vaccination (Source: Advanced Science)

Neutralizing Antibody Production

Webinar

Development of a Lymphoid Organ-Chip to Evaluate mRNA Vaccine-Boosting Strategies

In this on-demand webinar, Lisa Chakrabarti, PhD, from Institut Pasteur described how her team developed a Lymphoid Organ-Chip using the Emulate Chip-S1® Stretchable Chip to address the challenge of predicting vaccine immunogenicity in humans.

Part of the Human Emulation System®

The Human Emulation System is comprised of instruments, consumables, and software in a flexible, open format. The user-friendly platform gives researchers a window into the inner workings of human biology.
