VJLabs at the Terasaki Institute for Biomedical Innovation engineers next-generation organ-on-a-chip platforms and microphysiological systems that recapitulate human organ physiology and disease.
Founded in 2020 by Dr. Vadim Jucaud, a mentee of the late Dr. Paul I. Terasaki, the lab brings together immunology, microfluidics, tissue engineering, biomaterials, and biosensing to build in vitro models that accelerate drug discovery, reduce reliance on animal testing, and advance personalized medicine.
At the heart of VJLabs is our proprietary vascularized Tissueoid technology, which integrates perfusable microvascular networks with three-dimensional tissue constructs to create organ models with unprecedented physiological relevance. This platform serves as the foundation for five interconnected research programs spanning organ-on-a-chip engineering, transplant immunology, cancer biology, biosensing, and biomaterials.

Assistant Professor, Terasaki Institute for Biomedical Innovation
Dr. Vadim Jucaud is an Assistant Professor at the Terasaki Institute for Biomedical Innovation and the founder of VJLabs. He holds a Ph.D. in Immunology and Microbiology with specialization in transplant immunology and Human Leukocyte Antigen (HLA) immunobiology.
Dr. Jucaud began his research career in 2010 under the mentorship of Professor Paul I. Terasaki, working in the fields of histocompatibility and immunogenetics with a focus on HLA antibodies and the Humoral Theory of Transplantation. Over 12 years, he developed deep expertise in HLA immunogenetics, antibody cross-reactivity, immunogenic epitope characterization, and T and B cell immunomodulation.
In 2018, he received the American Transplant Congress Young Investigator Award for his work demonstrating the prevalence and impact of de novo donor-specific antibodies during a multicenter immunosuppression withdrawal trial in adult liver transplant recipients.
Motivated by this foundation and the multidisciplinary environment at TIBI, Dr. Jucaud established VJLabs in 2020 to pioneer immunocompetent organ-on-a-chip platforms at the intersection of HLA immunobiology, microfluidics, tissue engineering, biomaterials, and biosensing.
Our research spans organ-on-a-chip engineering, immunology, biosensing, biomaterials, and cancer biology, all converging on the vascularized Tissueoid platform to create clinically relevant human tissue models.
Engineering the next generation of human-relevant tissue models
The central pillar of VJLabs. We engineer vascularized, perfusable organ models including liver, blood-brain barrier, lymph node, and glioblastoma that recapitulate human physiology and disease.
What: Vascularized Tissueoid platforms with perfusable microvascular networks, immune cell access, and integrated biosensors.
Why: Conventional models lack vasculature, immune competence, and real-time readouts, limiting their predictive value for drug discovery and regulatory applications.
How: Scalable thermoplastic fabrication, modular chip architectures, and accessible manufacturing designed for academic, pharmaceutical, and regulatory adoption.
Decoding the immune response to improve transplant outcomes
We study how donor-specific HLA antibodies shape transplant outcomes by mapping antibody-antigen interactions, characterizing immunogenic epitopes, and developing computational models to predict immune responses.
What: HLA antibody characterization, epitope mapping, immunogenicity prediction, and computational donor-recipient matching using the E3 feature engineering software.
Why: Antibody-mediated rejection remains the leading cause of long-term graft loss. Predicting which mismatches trigger immune responses is critical for improving patient outcomes.
How: Our deep immunological expertise directly informs our organ-on-a-chip platforms, making them uniquely immunocompetent for modeling allograft rejection, tolerance pathways, and immunosuppressive strategies.
Personalized cancer models for better therapeutic decisions
We address critical gaps in cancer research through engineered tissue models for cancer vaccine screening, drug resistance studies, and embolic agent evaluation.
What: Lymph node-on-a-chip for cancer vaccine efficacy screening (including aging populations), glioblastoma-on-a-chip for pericyte-mediated drug resistance, and vascularized liver tumor model for embolic agent testing.
Why: Preclinical models fail to capture the complexity of human immune responses, especially in elderly patients who bear the highest cancer burden and are often overlooked in testing.
How: Our platforms recapitulate antigen presentation, T cell activation, tumor microenvironment mechanics, and age-dependent immune responses in controlled, human-relevant systems.
Turning organ-on-a-chip platforms into continuously monitored living systems
We develop and integrate label-free sensing technologies directly into our organ-on-a-chip platforms for continuous, real-time monitoring without disrupting the biological system.
What: PC-TIR optical biosensors for antibody/toxicity monitoring, TEER electrodes for barrier integrity, electrochemical immunosensors, and contact lens biosensors for ocular biomarker detection.
Why: Traditional drug screening relies on endpoint assays that miss dynamic cellular responses, contributing to a >90% clinical trial failure rate.
How: Sensors are embedded directly into chip devices, enabling multiplexed readouts that generate richer mechanistic data for regulatory submissions and clinical decisions.
From advanced hydrogels to clinically translatable therapeutics
We engineer advanced biomaterials that enhance the physiological relevance of our tissue models and enable standalone clinical applications in wound healing and regenerative medicine.
What: Tunable hydrogel platforms (ionogels, peptide hydrogels), oxygen-generating microparticles, natural rubber latex therapeutics, and nanofibrous scaffolds for tissue repair.
Why: Biomaterials that faithfully replicate native tissue properties are essential for both accurate in vitro modeling and direct therapeutic applications.
How: We integrate biomaterials into microfluidic platforms for real-time evaluation and develop standalone dressings and scaffolds for clinical use, including a pilot trial for diabetic foot ulcers.
Each technology addresses a specific barrier in biomedical research. Together, they form an integrated ecosystem for building clinically relevant human tissue models.




The missing vascular layer that makes organ models physiologically relevant
What: A proprietary platform that integrates perfusable microvascular networks with 3D tissue constructs, enabling nutrient delivery, immune cell trafficking, and drug transport that mirror in vivo conditions.
Why: Most organ-on-a-chip models lack functional vasculature, limiting their ability to model immune-mediated injury, drug distribution, and long-term tissue viability.
Immunocompetent by design: Built on 15+ years of HLA immunobiology expertise, our Tissueoids support controlled exposure to donor-specific antibodies and complement, immune cell trafficking, dendritic cell antigen presentation, T cell activation, immunosenescence modeling, and cytokine profiling.
Organ-specific models: Vascularized liver (regeneration, rejection, hepatotoxicity, embolization), blood-brain barrier (drug permeability, neurotoxicity), lymph node (cancer vaccine screening), and glioblastoma (drug resistance, TME modeling).

Accessible microfluidic infrastructure that brings organ models to any lab
What: Microfluidic chip systems that house and perfuse Tissueoid constructs with controlled flow, defined exposure conditions, and integrated electrode/sensor ports.
Why: Most organ-on-a-chip fabrication requires expensive cleanroom infrastructure, limiting adoption. Our scalable thermoplastic approach makes the technology practical for any research setting.
Key features: Scalable thermoplastic fabrication, modular chip designs adaptable to multiple organ contexts, integrated electrode and sensor ports, and perfusion systems supporting both short-term experiments and long-term culture (28+ days).
Design philosophy: Accessibility and cost reduction, making organ-on-a-chip technologies practical for broader adoption in academic, pharmaceutical, and regulatory settings.
Key publication: Small 2024


Transforming static tissue models into dynamically monitored living systems
What: Multiple sensing technologies embedded directly into organ-on-a-chip platforms for continuous, real-time monitoring of cellular responses without disrupting the biology.
Why: Traditional drug screening relies on endpoint assays that miss dynamic cellular responses, contributing to a >90% clinical trial failure rate.
PC-TIR optical biosensors: Label-free, real-time monitoring of monoclonal antibody secretion and drug-induced toxicity (with UT San Antonio).
TEER electrodes: Screen-printed electrodes for continuous barrier integrity measurement.
Electrochemical immunosensors: Reusable sensors for on-chip cellular differentiation and biomarker secretion.

Advanced materials bridging tissue modeling and clinical therapeutics
What: Novel biomaterials that enhance organ-on-a-chip physiological relevance and enable standalone clinical applications in wound healing and regenerative medicine.
Why: Faithful replication of native tissue mechanical and biochemical properties is essential for both accurate modeling and direct therapeutic translation.
Hydrogel platforms: Deep eutectic solvent-based ionogels with ultrafast gelation; peptide hydrogels with immunomodulatory properties; amyloid-mimicking hydrogels for neuronal studies.
Oxygen-generating biomaterials: Microparticles that downregulate HIF-1α, increase cardiac contractility, and mitigate ischemic injury.

Nanofibrous scaffolds: Granular porous microspheres enhancing cellular infiltration for diabetic wound healing.
Key publications: Adv. Funct. Mater. 2023 · Acta Biomater. 2023




Comprehensive molecular characterization of HLA mismatches for transplant prediction
What: A feature engineering software that generates over 400 molecular features from any donor-recipient HLA mismatch, identifying which properties are associated with antibody development and transplant rejection.
Why: Existing tools assess HLA immunogenicity with single metrics. E3 integrates all available approaches into one unified framework for comprehensive risk assessment.
Feature coverage: HLAMatchmaker eplet scores, PIRCHE-II predicted epitopes, electrostatic and hydrophobicity differences, antibody-verified epitopes, plus novel VJLabs-developed features.
Applications: Predicting de novo donor-specific antibody development, identifying high-risk vs. low-risk mismatches at the molecular level, optimizing donor-recipient matching, and supporting ML approaches to immunogenicity assessment.
E3 has been used in multiple published studies and is currently being developed for broader availability.
