Conclusion
This would support the use of these combinations for clinical purposes, especially in the spinal fusion and reconstruction setting.
Material and methods
In the present study, we have compared the in vitro expansion capacity, viability, immunophenotype (both explored by flow cytometry) and multi-differentiation ability of MSC cultured in the presence of either titanium or tantalum fragments. The adherence of MSC to either metal was demonstrated by electron microscopy.
Methods
In the present study, we have compared the in vitro expansion capacity, viability, immunophenotype (both explored by flow cytometry) and multi-differentiation ability of MSC cultured in the presence of either titanium or tantalum fragments. The adherence of MSC to either metal was demonstrated by electron microscopy.
Results
Both metals were able to carry MSC when transferred to new culture flasks. In addition, our study shows that culture of MSC with titanium or tantalum improves cell viability and maintains all their biological properties, with no significant differences regarding the metal employed.
