Time-resolved transcriptomic profiling of mammary gland tissue during ductal morphogenesis, lactation activation, and involution in sows

This study constructed a time-resolved transcriptomic atlas of porcine mammary gland development, lactation, and involution, revealing gene expression dynamics, candidate pathways, and molecular signatures associated with structural and functional changes in the mammary gland, and providing potential targets and a theoretical basis for improving sow lactation performance and regulating mammary function.
