UK Research Institutions Unite to Advance Non-Animal Technologies in Veterinary Research

UK Institutions Forge Ahead with Non-Animal Technologies in Veterinary Research

In a landmark development announced on January 26, 2026, four premier UK research institutions have banded together to pioneer non-animal technologies (NATs) specifically tailored for veterinary research. The Biotechnology and Biological Sciences Research Council (BBSRC) is funding this collaborative effort involving The Pirbright Institute, Moredun Research Institute, The Roslin Institute at the University of Edinburgh, and the Royal Veterinary College (RVC). This initiative marks a significant step toward reducing reliance on live animals in studies of animal health, infectious diseases, and immunity, aligning with broader national goals to refine and replace traditional methods. 71 69

The collaboration addresses a critical need in veterinary science, where animal models have long been the gold standard but often fall short in reproducibility and translatability to real-world applications. By developing advanced laboratory-based models, the partners aim to create more predictive tools for pathogens affecting livestock and aquaculture species, ultimately benefiting food security, animal welfare, and public health.

Understanding Non-Animal Technologies: A Primer for Veterinary Applications

Non-animal technologies, often abbreviated as NATs, encompass a suite of innovative approaches that replace or supplement whole-animal experiments. These include cell-based models derived from stem cells, multicellular organoids mimicking organ structures, co-cultures combining various cell types, and sophisticated tissue slice cultures with air-liquid interfaces to simulate physiological environments. Unlike traditional in vivo testing, NATs leverage human- or animal-relevant cells grown in controlled conditions, integrated with computational modeling and artificial intelligence (AI) for data analysis. 70

In veterinary research, NATs are particularly promising for modeling infections like foot-and-mouth disease virus (FMDV) or influenza in species such as pigs, cattle, sheep, chickens, and fish. For instance, stem cell-derived cells can differentiate into respiratory epithelial layers, allowing researchers to observe viral entry and immune responses without infecting live animals. This shift not only minimizes ethical concerns but also enhances scientific precision by reducing biological variability inherent in whole-animal studies.

The Powerhouses Behind the Collaboration

Each institution brings unique strengths to the table. The Pirbright Institute excels in virology and immunology, with Dr. Wilhelm Gerner leading efforts to characterize immune features in NATs. "A central challenge for non-animal models is not simply generating them, but understanding in detail what cell types and immune features they actually represent," Gerner noted, emphasizing rigorous immunological profiling. 71

Moredun Research Institute, focused on livestock diseases, is enhancing models with immune cells under Principal Investigator Dr. David Smith. The Roslin Institute, renowned for cloning Dolly the sheep, develops models for understudied species, as highlighted by Interim Director Professor Mark Stevens. The RVC, the UK's oldest veterinary school, contributes molecular immunology expertise via Professor Dirk Werling, who envisions "a trusted set of non-animal tools for key veterinary species." 71 69

This synergy between research institutes and universities underscores the higher education sector's pivotal role. For aspiring researchers, opportunities abound in research jobs at these institutions, where cutting-edge projects intersect with practical training.

Core Technologies in Focus: From Organoids to Immune-Enhanced Cultures

The project targets a progression of model complexity. Starting with single-cell types from induced pluripotent stem cells (iPSCs)—reprogrammed adult cells that mimic embryonic stem cells—researchers will build toward organoids, three-dimensional structures replicating organ architecture. Co-cultures integrate epithelial, immune, and stromal cells to study interactions during infection.

Advanced setups include precision-cut tissue slices preserving native architecture and air-liquid interface cultures, where cells at the surface encounter air like lung linings do. These will incorporate primary immune cells to probe early responses, crucial for vaccine design against livestock pathogens. Harmonized protocols ensure comparability across species, fostering reproducibility—a longstanding issue in animal research where genetic and environmental factors vary widely.

• Cell-based models: Stem cell differentiation for target tissues.
• Multicellular organoids: Simulating organ-level responses.
• Tissue slices and interfaces: Retaining in vivo-like complexity.

Validation: The Key to Credibility and Adoption

Validation is the cornerstone, comparing NAT outputs to biobanked tissues from prior infection studies. For example, models challenged with influenza or FMDV will be benchmarked against ex vivo data, quantifying metrics like viral replication rates and cytokine profiles. This direct correlation establishes biological relevance, addressing skepticism that NATs oversimplify complex systems.

Cross-institutional standardization minimizes lab-to-lab variability, a boon for regulatory acceptance. In veterinary contexts, validated NATs could expedite vaccine batch testing, reducing animal numbers in potency assays. This aligns with the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) efforts, which have already funded infrastructure for NATs. 70

Professionals in higher education career advice note that expertise in NAT validation is increasingly sought in lecturer jobs and faculty positions.

Syncing with National and Global Strategies

This collaboration dovetails with the UK government's November 2025 strategy, "Replacing Animals in Science," committing £30 million to a preclinical hub and establishing the UK Centre for Validation of Alternative Methods (UKCVAM) by 2026. Timelines include phasing out rabbit pyrogen tests by 2025 and botulinum potency animal tests by 2027, with veterinary medicines prioritized via the Veterinary Medicines Directorate (VMD). 72

NC3Rs' NAT roadmap, dating to 2015 but revitalized, supports feasibility studies and special interest groups, positioning the UK as a leader in a market projected at $29.4 billion globally by 2030. Internationally, alignment with OECD and VICH guidelines ensures NATs gain traction beyond borders. For detailed insights, see the government strategy document. 72

Benefits: Ethical, Scientific, and Economic Gains

NATs promise multifaceted advantages. Ethically, they reduce animal suffering—UK labs used over 3 million procedures in 2023, many in veterinary contexts. Scientifically, human-relevant (or species-specific) models improve predictivity; animal data fails 90% in translating to human trials, a figure NATs aim to slash.

Economically, faster development cuts costs: drug attrition drops, vaccines reach markets quicker amid threats like avian flu. For UK agriculture, robust NATs safeguard £14 billion livestock exports. Stakeholders from industry to welfare groups applaud the move, with LinkedIn comments calling it "brilliant" and "humane." 69

• Enhanced reproducibility via controlled conditions.
• High-throughput screening for rapid iteration.
• Ethical compliance boosting public trust.

Challenges and Pathways Forward

Despite promise, hurdles remain: NATs must replicate immune dynamics fully, scale for regulatory volumes, and secure funding amid budget pressures. Complex endpoints like chronic disease progression demand integrated approaches—AI for data integration, bioprinting for vascularized organoids.

The consortium's conference on March 26-27, 2026, at Roslin Institute will tackle these, fostering stakeholder dialogue. Long-term, open-access protocols and training programs will democratize access. For vet students and postdocs, this heralds a paradigm shift; postdoc positions in NATs are surging.

Spotlight on Higher Education: Training the Next Generation

Universities like RVC and Edinburgh lead, integrating NATs into curricula. RVC's immunology programs now emphasize organoids, preparing graduates for university jobs in translational research. Roslin's PhD cohorts validate models against genomic datasets, blending wet-lab and computational skills.

This positions UK higher ed globally, attracting talent amid Brexit challenges. Career advice: Build interdisciplinary profiles—cell biology, bioinformatics, ethics—for roles in research assistant jobs.

Real-World Impacts and Future Horizons
