(A) Cytotoxicity analysis of human osteosarcoma cell line (MNNG/HOS) against Se-HAp and its modification with different concentrations of catechins, i.e., 5% (CC/Se-HAp1), 7% (CC/Se-HAp2), and 10% (CC/Se-HAp3) relative to control. (B) Viability analysis of human bone marrow stem cells (hBMSCs) on Se-HAp and its modification with 5% catechins (i.e., CC/Se-HAp1) and 10% catechins (i.e., CC/Se-HAp3) relative to control. (C) ROS inhibitor attenuated the cytotoxic effect of nanoparticles, which resulted in higher cell viability. *p < 0.01, **p < 0.001, ***p < 0.0001 indicate significant differences of CC/Se-HAp-3 in comparison with Se-HAp.
