ABSTRACT
PURPOSE: To explore the characters of attachment, proliferation and osteogenic differentiation of stem cells from goat deciduous teeth (SGDs) cultured on akermanite ceramic. METHODS: SGDs were collected with enzyme digestion, and cultured. Under culture condition in growth medium, actin filament labeling and CCK-8 analysis were used to reveal attachment and proliferation. Expression level of alkaline phosphatase (ALP) and osteogenic differentiation genes (ALP, COL I, OPN and OCN) were examined by pNPP method and real-time PCR. The data was analyzed using SPSS 13.0 software package. RESULTS: Compared with ß-TCP, SGDs seeded on akermanite ceramic not only spread out better, but also grew faster since day 4. In osteogenic medium, cells of akermanite group had stronger ALP activity at day 4 and 7. The gene expression of akermanite was more than the ß-TCP group. The gene OCN expression level increased significantly at day 7 (P<0.01). CONCLUSIONS: SGDs can attach and grow well on akermanite ceramic. Compared with ß-TCP, akermanite ceramic shows an advantage in osteogenic differentiation of SGDs.
