A Commentary on “Evaluation of the in vitro Bioactivity of Bioceramics”

The interesting article reported in Bone and Tissue Regeneration Insights by Wu and Xiao entitled “Evaluation of the in vitro bioactivity of bioceramics” contrasts two methods (Simulated body fluid (SBF) and cell culture experiments) which have been commonly used to evaluate the in vitro bioactivity of bioceramics. Limitations in estimating the bioactivity of bioceramics using both methods have been reviewed. Therefore, Wu and Xiao suggest the combination of these two methods to evaluate the bioactivity of bioceramics can improve the screening efficiency for the selection of bioactive ceramics for bone regeneration.
