Abstract:
Objective
To investigate the biological effects of the cultured dog bone marrow stromal cells (BMSCs) with the novel porous scaffold poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/sol gel bioactive glass (PHBV/SGBG).
Methods
Dog BMSCs were cultured on the PHBV/SGBG scaffolds in vitro. The cell attachment and distribution on the scaffold were observed under a scanning electron microscope (SEM). MTT assay and alkaline phosphatase(ALP) activity measurement were used to detect the effects of the PHBV/SGBG scaffolds on cell proliferation and differentiation.
Results
Dog BMSCs firmly attached to and grew well on the surface of PHBV/SGBG scaffolds. Obvious cell processes stretched into the micro-pores structure.After 3-day- and 6-day-culture with the PHBV/SGBG scaffolds, the proliferation and differentiation of dog BMSCs were improved.
Conclusion
It suggested that the compound of dog BMSCs and PHBV/SGBG scaffold with good biological properties would be a potential method for periodontal tissue engineering.
