Elemental concentration of silicon (Si) in cell culture medium after 3, 7 and 14 days of incubation in presence of CaP-A and CaP-I coatings made with 0, 1, 5 and 10 mM of Si and CaP-M coatings with 0 and 1 mM of Si. Data are shown as mean ± standard deviation from n = 3 samples. Results showed an increase in Si concentration in the cultured medium of CaP-A 10 mM and CaP-I 5 and mM. Cell culture medium from CaP-M revealed a decrease in Si concentration after 14 days
