The purpose of this study is to optimize the isolation and culture method for muscle stem cells, called satellite cells, in the breast muscle of meat-type chicken (Broiler). Satellite cells play pivotal roles in muscle development, growth, and muscle regeneration. One challenge of primary cell isolation is efficient and effective purification from a mixture of cell types, while maintaining viability and achieving high yield. Here, we developed a protocol enabling high yield and purity of primary satellite cells isolation and optimized culture conditions. We obtained about 95% purified satellite cells with high viability, and this method is simple and cost-effective compared to alternative cell sorting techniques that require cell-labeling steps and expensive equipment. Thus, this optimized satellite cell isolation and culture may be valuable for in vitro studies of cellular and molecular mechanisms responsible for muscle diseases (e.g., white striping and wooden breast) and the nutritional regulation of muscle development in broiler.
