Laboratory Animal Services

The Laboratory Animal Services Facility team supports Stowers research programs that include the study of animal models to better understand biological processes of health and disease.

Overview of Services

Research Services

The Laboratory Animal Services Facility (LASF) provides the Institute’s research staff with AAALAC-accredited laboratory animal care and support services using state-of-the-art equipment, advanced technology, and a progressive staff in a premier animal facility. The LASF is responsible for maintaining the health and welfare of the mammalian species involved in research studies at the Institute, mice and rats.

The facility is designed to maintain animal projects under rigorous barrier conditions with every effort made to limit the introduction of undesirable pathogens that may impact the integrity and reproducibility of the research data. The facility is fully accredited with AAALAC International and all housing, husbandry practices, and veterinary care for the animals are in compliance with the Guide for the Care and Use of Laboratory Animals, and the Public Health Service Policy on Humane Care and Use of Laboratory Animals, as well as all other institutional, state, and local regulations.

Lab Animal Services’ Teams

The Lab Animal Services (LAS) facility, a core services unit, is responsible for care and maintenance of rodents at the Stowers Institute. The LAS provides research staff training and support in the use of laboratory mice by maintaining exemplary standards and effective resource management from our four dedicated teams in the areas of husbandry, technical services, core breeding and importation.


An extensively trained, well-educated staff provides the highest level of animal husbandry and care that includes the daily feeding, health observation, and veterinary care of each animal to enhance the research, education, and life sciences at the Stowers Institute.

Technical services

Proficient, highly skilled technicians are designated to each investigative team to assist the lab and its members with a wide range of procedures often used in animal studies. These technicians have the responsibility for the efficient management of the lab’s animal colony, allowing the lab members to devote more time to their work at the bench.

Core Colony

The core breeding colonies at the Stowers Institute were created to provide a unique situation where commonly used mouse stocks and strains could be made readily available at a reduced cost to our research teams. Maintaining in-house breeding colonies allows our research staff access to clean, healthy mice at the optimal age, gender and/or weight for their research projects and other core services.

Importation Facility

The importation facility allows Stowers’ researchers the ability to ship and receive mice from nearly anywhere around the world. With a designated staff assignment and separate environments, mice with known or unknown pathogen statuses can be imported, quarantined and rederived to a pathogen-free status for research.
