Modify and reconstruct embryonic stem cells (ESCs) to establish a stable and intuitively observable ESC system; 2. Combining the normal developmental process of the crystalline lens, based on the in vitro induction of lens organoids via the "fried egg" method, investigate the key processes and mechanisms of in vivo induced differentiation of ESCs, identify the key precursor cells that affect differentiation outcomes, screen out seed cells suitable for implantation in regenerative crystalline lens research, and establish a platform for large-scale acquisition of target seed cells; 3. Screen suitable scaffold materials and modify them to support the implanted seed cells, and establish a safe, efficient and stable cell-material hybrid system; 4. Explore the regulatory factors and their modes of action during crystalline lens development, screen out one or two key regulatory factors, and apply them to regenerative crystalline lens research based on their properties; 5. Improve existing mature surgical procedures, design appropriate surgical methods to ensure stable fixation of the cell-material hybrid system post-surgery, and maintain the stability and efficiency of the in vivo microenvironment for regenerative crystalline lens research.
