The Phenotyping Core (Core B) is designed to evaluate the functional properties of muscles, joints, and whole animals in animal models created by the various Center investigators or directly in human muscle. The Phenotyping Core will interface with the High Throughput Cell Sorting Core and the Imaging Core by helping Center investigators identify the appropriate functional evaluation of muscle, with special consideration of the specific manipulation created by the Center investigator. The quantitative functional evaluation conducted by the Phenotyping Core will often be combined with structural data obtained from the Imaging Core thereby providing possible mechanistic explanations for any functional effects that are found. Thus, the Phenotyping Core will provide accessibility to sophisticated physiological and biomechanical testing capabilities to all Center investigators.
The Specific Aims of the Phenotyping Core are: 1) To provide training and technical assistance in skeletal muscle identification, dissection and mounting for isolated contractile and metabolic studies of isolated muscles. 2) To provide training and technical assistance in developing specialized
One of the great strengths of the Phenotyping Core are the multiple scale levels on which function can be assessed including the whole animal (on treadmills), whole joint (via torque motors), whole muscle (using in vitro testing) and isolated single fibers (also using in vitro testing). Thus, this Core plays an essential role in the proposed Center's long-term goal to achieve a comprehensive understanding of multi-scale structure function relationships in skeletal muscles. Since most of the devices in the core are highly specialized, they are generally unavailable to Center investigators, except through mechanisms such as the P30. This core thus fills a significant void in the local San Diego muscle research community.
