For angiogenesis, lower expression was also observed in the PO group compared to the BC group, a result similar to that published in 2014 by Chen et al. [46], who, when assessing angiogenesis in biphasic bioceramics with different proportions of HA and β -TCP, concluded that the higher the β -TCP phase, the higher the expression for VEGF, inducing an increase in the neovascularization of biphasic bioceramics. This evidence concerns the gene VEGFA and breast cancer.
