Calcium concentration in nano-coated PET fiber artificial ligament culture medium. Calcium concentration on the 8th, 10th, 12th, and 14th day was recorded. Calcium concentration in SrSiP was significantly lower than in the non-coated sample on the 8th, 10th, 12th, and 14th day of the culture supernatant. The solid and broken lines indicate the data obtained in SrSiP and non-coated samples. Data are shown as the mean ± SD. Asterisk indicates p < 0.05 vs. non-coated group (control)
