Abstract: Objective: To observe the effects of cinnamaldehyde (CA) on the proliferation and differentiation of MC3T3-E1 osteoblasts induced by high glucose. Methods: MC3T3-E1 cells were cultured in glucose (25 mmol/L) with 0 (control), 10, 20, and 40 mg/L CA. Cell proliferation, ALP activity, and alizarin red staining was measured. Morphology of the cytoskeleton was observed by confocal laser scanning microscope. Expression levels of osteogenesis related genes OCN mRNA were detected by real-time PCR. Results: CA could promote the proliferation and ALP activity of osteoblasts in high glucose environment (P<0.05). The number and the volume of mineralized nodules increased. The expression of OCN mRNA in the experimental group was significantly up-regulated (P<0.05). When the concentration of CA was 10mg/L and 20mg/L, the cell spreading area was increased and the cytoskeleton was clearer. Conclusion: CA can promote the proliferation and differentiation of MC3T3-E1.
