The Marsico Lung Institute/UNC Cystic Fibrosis Center Animal Models Core is dedicated to providing access and specialized expertise to conduct in vivo studies with animal models (primarily mouse) that provide insights into pulmonary disease pathophysiology and treatment. Core users are typically collaborating academic investigators and industry partners, through Spirovation. The Animal Models Core has been involved in the generation and characterization of over 25 lines of genetically modified mice (transgenic, knockout, or knockin) for a variety of collaborators over the years, and has also conducted studies in other species (rabbit, hamster, rat, guinea pig) for investigator-initiated projects. The Mouse Models Core laboratory is located on the seventh floor of Marsico Hall (Rm 7229L, 7224, 7122a), with mouse colonies housed in the Genetic Medicine Division of Comparative Medicine (DCM) facility, and dedicated DCM BSL2 cubicles in Marsico Hall (B107, 7229AA). Main activities of the Core include:

Mouse line development and colony management:

The development of new lines is highly dependent upon a collaboration with the UNC Transgenic Mouse Core, and more recently to the use of transgenic lines obtained from international resources, such as KOMP, EUCOMM, and the MRRCC. Once founders are identified, lines are validated, expanded and maintained to generate experimental cohorts or provide breeder pairs to external investigators. Publications utilizing these mouse models in a variety of context can be found here.


The Animal Models Core supports research covering many aspects of lung disease biology, including airway mucus clearance, bacterial and viral pathogenesis, injury/repair, and inflammation. Expertise in several aspects of in vivo experimentation is provided including model selection, experimental challenges, pharmacological treatments, and comprehensive respiratory phenotyping for both upper and lower airways. Routine techniques include: survival and non-survival surgeries, health status monitoring, bronchoalveolar lavage, middle ear lavage, tissue harvest, preparation of samples for cytological, histological, microbiological, biochemical, immunological, and rheological analyses, and primary culture of tracheal and nasopharyngeal airway cells.  Histological services (processing, embedding, sectioning) are routinely provided through UNC-based Histology Cores (Pathology Services Core, Histology Research Core, or Center for Gastrointestinal Biology and Disease Histology Core).

Phenotyping Figure
Assessment of lung inflammation, mucus obstruction, and mucous secretory cell metaplasia are routinely performed in the MLI Animal Models Core using a comprehensive phenotypic panel that includes bronchoalveolar lavage, differential cell counts, multiplex inflammatory mediators analysis, mucin agarose western blots, and histopathology/morphometric analyses. Adapted from Livraghi A. et al., J Immunol., 2009; Livraghi-Butrico A. et al., Physiol Genomics, 2012.

Collaboration with experts in the field also allows access to specialized equipment/techniques, including aerosol administration through a nose-only inhalation exposure system (DSI Inhalation exposure system, in collaboration with Dr. Gregory Smith); pulmonary function test (SCIREQ flexivent system), mucociliary clearance assay (in collaboration with Dr. Barbara Grubb), nasal mucociliary clearance by pinhole gamma scintigraphy, in collaboration with the Center for Environmental Medicine, Asthma and Lung Biology); characterization of ex vivo tissue or cell culture bioelectrical properties (Drs. Barbara Grubb and Martina Gentzsch).

DSI Buxco Inhalation System
DSI Buxco Inhalation System includes stackable units (2 towers with 14 ports each: 10 ports available for exposure, 4 ports occupied by sampling devices and sensors). Suitable for integrated plethysmography measurements (upon request and funding availability).
NAC and P3001 Comparison Figure
Translational projects leverage the expertise of the MLI Animal Models Core to provide proof-of-principle data during the development of new therapeutics. In this panel, our model of airway mucus obstruction (βENaC-Tg or Scnn1b-Tg mouse) was used to demonstrate the enhanced efficacy in mobilizing airway mucus plugs of a prototype compound (P3001) as compared to standard-of-care (NAC, N-acetylcysteine) or vehicle (NS, normal saline).

Regulatory compliance:

The Animal Models Core provides guidance and assistance in matters regarding regulatory compliance with UNC Environmental Health and Safety (EHS), Office of Animal Care and Use (OACU), and Division of Comparative Medicine (DCM) guidelines.


Spirovation is a specialty contract research organization (CRO) affiliated with the Marsico Lung Institute  and its mission is to empower breakthrough drug development in respiratory medicine by providing leading scientific expertise and the broadest array of translational medicine capabilities in respiratory research, including those provided by the Animal Models core.
