Mouse Behavioral Phenotyping MBPF

Mouse Behavioral Phenotyping MBPF

Rationale.The central nervous system (CNS) is the most complex structure of the animal organism both in terms of its development and function. CNS phenotyping requires special skills and equipment, and combination of several research approaches, including behavioural analysis, pharmacological profiling, electrophysiology, imaging, histopathology. Behavioural phenotyping of laboratory rodents is highly important and relevant approach in basic biomedical research. For instance, the goal of the International Mouse Phenotyping Consortium (IMPC, is to discover functional insight for every gene by generating and systematically phenotyping ~20,000 knockout mouse strains. Eventually, these mice will be available for research community worldwide for specific hypothesis-driven experiments, and there will be high demand for expertise in different areas of phenotyping. Modelling complex neuropsychiatric, neurodegenerative and neurological disorders in animals is not possible without reliable behavioural readouts and endpoints. Moreover, it can be argued that behaviour of a living organism is affected by any manipulation or treatment (genetic or non-genetic). Therefore, behavioural analysis could be also applied in studies involving any organ system beyond brain and CNS (e.g. metabolism, cardiovascular system, endocrinology, immunology, cancer research etc.). Adopting this strategy can significantly enhance validity of the research results. Therefore, maintenance of core facilities providing both equipment and expertise in broad field of rodent physiology and behaviour is essential for maintaining a competitive international level and further development of basic and applied science.

Mouse Behavioral Phenotyping Facility (MBPF) is a state-of-the-art core facility providing equipment and professional assistance (including design, implementation, analysis, presentation and interpretation) for researchers interested in behavioural examination of the mouse models. MBPF is a partner in FinnMouse technology platform (supported by model organisms scientific network by Biocenter Finland), operating at the Laboratory Animal Center (LAC) of University of Helsinki. This combination creates a strong infrastructure to support the research with rodent models.

Researchers interested in using the facility are advised to contact the director for discussing the details of planning and conducting the experiments. Access is regulated by terms of service and user fees are applied according to the price list.
