Abstract
Cell culture technology, as one of the core technologies in the field of tissue engineering and regenerative medicine, has achieved remarkable progress in recent years in terms of biomaterial development, cell expansion, and functional construction. This study aims to systematically investigate the current applications and future development directions of cell culture technology in tissue engineering and regenerative medicine by analyzing the mechanisms through which different culture systems influence cell behavior and elucidating their critical roles in promoting tissue repair and organ replacement. A combined approach of literature review and experimental validation was employed to comprehensively evaluate the advantages and limitations of traditional two-dimensional culture, three-dimensional scaffold culture, and dynamic bioreactor culture. Based on the latest research findings, a high-throughput cell culture strategy utilizing microfluidic chips was proposed. The results indicate that novel cell culture technologies can effectively mimic the in vivo microenvironment, significantly enhancing cell viability and functional differentiation efficiency while providing new possibilities for personalized medicine. The innovation of this study lies in the first-time integration of microfluidic technology with multiscale biomechanical stimulation, enabling precise reconstruction of complex tissue structures and validating its feasibility in cartilage, bone, and nerve tissue repair. Furthermore, the study emphasizes the importance of standardized culture protocols, laying a theoretical foundation for advancing cell culture technology from laboratory research to clinical translation. Overall, the continuous optimization of cell culture technology injects new momentum into the development of tissue engineering and regenerative medicine, and future research should focus on interdisciplinary integration and clinical application verification to achieve higher levels of tissue repair and functional reconstruction.
