Figure 3From: Immobilizing hydroxycholesterol with apatite on titanium surfaces to induce ossificationEffects of hydroxycholesterol on (A) cell viability and (B) ALP activity. C3H10T1/2 cells were cultured on samples with apatite coating or adsorbed apatite/HC coating in growth medium for 6 d. Three kinds of hydroxycholesterol were chosen to prepare the adsorbed apatite/HC coating: 25-HC, 22(S)-HC, and 20α-HC. The values represent the mean ± standard deviation (n =3).Back to article page
