Figure 4From: Immobilizing hydroxycholesterol with apatite on titanium surfaces to induce ossificationNormalized ALP activities with respect to total protein at day 6. C3H10T1/2 cells were seeded on samples with apatite coating, sandwich-like apatite/20α-HC/apatite coating, and adsorbed apatite/20α-HC coating in mineralizing medium for 6 d. The values represent the mean ± standard deviation (n =3).Back to article page
