Abstract: Objective: To explore the possibility of gelatin sponge as a scaffold of mouse embryonic stem cells (ESCs) in vitro cultivation and to investigate the effect of glucose level on osteogenic differentiation of mouse ESCs. Methods: Mouse ESCs were cultured in vitro, and the dispersed cells were implanted into absorbable gelatin sponge for osteogenic induction. Three groups were set in the study: high-glucose-level group, low-glucose-level group and spontaneous differentiation group. After 7 and 14 days of osteogenic differentiation, the matrix mineralization was detected by alizarin red S staining. Results: After 7 and 14 days of osteogenic induction, low-glucose-level group had a higher percentage of alizarin red S positive cells, compared with high-glucose-level group and spontaneous differentiation group(P<0.05). Conclusion: Gelatin sponge can be used as a scaffold for culturing mouse ESCs in vitro study. High glucose level inhibits osteogenetic differentiation of mouse ESCs in the 3D culture system.
