ABSTRACTOptogenetics, a revolutionary technique leveraging light stimulation for precise cellular control, holds immense potential in regenerative medicine. Offering unparalleled spatial and temporal accuracy, the entrance of optogenetics into tissue engineering and regenerative medicine (TERM) empowers researchers to modify genes precisely and reversibly, control signal pathways and antibodies, as well as alter biomaterial properties. Optogenetics provides unprecedented control in the manipulation of physiological regeneration, replication of intricate developmental processes, and tissue engineering in a laboratory setting. Although further investigation is required for the safe and feasible injection of optogenetic systems into human bodies, the use of optogenetics has already led to a great amount of research on several tissues and systems. It has found diverse applications in TERM of skin and connective tissue, endothelium, bone, cartilage, and muscle; with researchers leveraging optogenetics for precise control over the in vitro or in vivo production of these tissues, the investigation of critical proteins and pathways, the creation of light‐controlled wound coverings and even as a tool for directional tissue growth in living subjects. Optogenetics emerges as a transformative force in shaping the future of medical science, demonstrating a pivotal role in advancing regenerative medicine and paving the way for innovative therapeutic strategies.
