Key Responsibilities and Required Skills for Xenotransplant Research Specialist

🎯 Role Definition

The Xenotransplant Research Specialist is a multidisciplinary scientist who designs, executes, and interprets preclinical xenotransplantation studies to support translational goals (porcine-to-human organ and tissue transplantation). This role blends surgical and veterinary techniques, molecular and cellular immunology, gene‑editing validation (e.g., CRISPR/Cas9), pathogen surveillance (PERV, porcine viruses), and GLP/GMP‑aligned data generation needed for regulatory submissions. The Specialist will work closely with surgical teams, process development, quality/regulatory affairs, and external collaborators to advance xenograft survival, limit immune rejection, and de-risk clinical translation.

Core Responsibilities

Primary Functions

Design, plan and lead complex preclinical xenotransplantation experiments (cardiac, renal, hepatic, islet, or composite tissue) including study protocols, endpoints, timelines, and resource allocation to generate robust translational data for IND-enabling studies.
Perform and supervise surgical implantation and explantation procedures in large animal models (porcine models), maintaining sterile technique, perioperative care, anesthesia management and post‑op monitoring aimed at maximizing xenograft viability and longevity.
Develop, validate and execute molecular and cellular assays to evaluate rejection, immune responses, and graft function: flow cytometry immunophenotyping, ELISA, multiplex cytokine panels, qPCR/RT‑qPCR, droplet digital PCR, and NGS assays for donor and recipient immune profiling.
Plan and execute gene editing verification and characterization (CRISPR/Cas9 and related platforms) for engineered donor pigs: sequencing validation, off‑target assessment, genotyping pipelines, and phenotype confirmation relevant to antigen presentation and immunogenicity.
Lead infectious agent screening and pathogen surveillance programs for donor herds and experimental cohorts, including PERV detection/quantification, porcine viral PCR panels, serology, bacteriology, mycoplasma, and sterility testing in compliance with biosecurity and regulatory expectations.
Implement and maintain GLP-like documentation for preclinical studies: study protocols, SOPs, raw data capture, electronic notebooks, data audit trails, deviation reporting and final study reports suitable for regulatory review (FDA, EMA).
Optimize immunosuppression regimens and biologic intervention schedules (monoclonal antibodies, costimulation blockers, complement inhibitors) in coordination with pharmacology and clinical strategy teams to reduce acute and chronic rejection in xenograft models.
Coordinate ex vivo organ perfusion, machine perfusion protocols, and viability assays to support organ procurement, preservation and transplantation endpoints used in translational device and organ studies.
Conduct histopathology and immunohistochemistry interpretation workflows; coordinate with veterinary pathologists for rejection scoring, thrombosis, complement deposition, and tissue‑level assessment of xenogeneic responses.
Generate and present high‑quality data packages, slide decks and technical reports to cross‑functional teams, leadership, and external collaborators; contribute directly to regulatory briefing documents, IND packages and grant applications.
Mentor and supervise junior scientists, technicians and surgical staff; provide hands‑on training in large-animal surgery, assay performance, biosafety, and documentation best practices to build team capability.
Manage vendor relationships and outside laboratory collaborations for specialized testing (viral clearance, deep sequencing, specialized pathology) and ensure subcontractor data meets quality and timeliness expectations.
Lead troubleshooting and root-cause analyses when xenograft failure or unexpected immune phenomena occur; propose and test iterative experimental modifications to address immunological, infectious, or coagulation challenges.
Integrate histology, functional metrics (e.g., serum creatinine, cardiac output), and immunophenotyping data into reproducible analytical pipelines to support decision-making and hypothesis generation.
Support scaling of donor animal breeding and herd health programs by advising on genetic engineering priorities, pathogen monitoring, and herd management practices aligned with xenotransplant translational goals.
Ensure all animal work is designed and executed in compliance with IACUC, AAALAC and institutional animal care regulations; prepare protocols, amendments, and assist with IACUC reviews and inspections.
Participate in risk assessment and biosafety planning for xenogeneic material handling, inactivation procedures, waste management, and lab infrastructure requirements for containment and cross‑contamination prevention.
Support cross-functional translational strategy by synthesizing preclinical internal data and published literature, proposing go/no-go criteria for advancing specific organ or modification strategies to clinical development.
Drive continuous improvement of laboratory operations: refine SOPs, implement assay standardization, lead qualification of instruments and maintain calibration and reagent inventory to ensure reproducible high-quality data.
Lead data governance and data integrity practices relevant to xenotransplant studies, ensuring datasets are searchable, well-annotated, and exportable for downstream bioinformatics, regulatory submissions and IP filings.
Actively monitor scientific literature, clinical xenotransplant milestones, regulatory guidance, and competitor activities to inform program direction and maintain scientific leadership in xenotransplantation.
Facilitate and represent the program in cross-institutional consortia, academic collaborations, and industry partnerships including co-authorship of manuscripts and presentations at scientific meetings focused on transplantation and gene editing.
Participate in budgeting, resource planning and grant writing efforts to secure funding for preclinical xenotransplant programs and to support long-term translational pipelines.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis across xenotransplantation datasets (immune profiling, viral surveillance, graft outcomes) to answer program questions and inform experiments.
Contribute to the organization's translational data strategy and roadmap for xenotransplantation, including assay harmonization, sample biobanking and metadata standards to accelerate regulatory readiness.
Collaborate with clinical, regulatory, and manufacturing teams to translate preclinical endpoints into clinical trial designs and regulatory strategies (IND/IDE submissions, risk mitigation).
Participate in project sprint planning, milestone definition and agile ceremonies within cross-functional translational teams to ensure timely delivery of preclinical assets.
Provide scientific input to quality systems and change control processes when assays or surgical procedures are updated for GLP/GMP alignment.
