Horse muscle tissue pieces and blocks are high-quality research biospecimens widely used in comparative physiology, veterinary pathology, musculoskeletal biology, regenerative medicine, and translational biomedical research. Equine skeletal muscle shares important metabolic, structural, and functional adaptations with that of highly trained human athletes, making it a well-recognized comparative model for investigating muscle fiber composition, exercise physiology, mitochondrial function, muscle regeneration, metabolic adaptation, and myopathies. Fresh-frozen or appropriately preserved horse muscle tissues are valuable for histopathology, immunohistochemistry (IHC), immunofluorescence, and molecular and cellular analyses, including transcriptomics, proteomics, and metabolomics. These specimens support studies of exercise-induced muscle remodeling, satellite cell activation, inflammatory responses, fibrosis, oxidative metabolism, glycogen storage disorders, and inherited equine muscle diseases, including polysaccharide storage myopathy (PSSM) and recurrent exertional rhabdomyolysis (RER). Their relevance to veterinary and comparative biomedical research makes equine muscle tissues an important resource for investigating skeletal muscle physiology, adaptation, and disease.
