Attachment, proliferation and ALP activity of BMSCs on the scaffolds. (A) Adhesion of BMSCs cultured on uncoated and Ta-coated scaffolds at 2, 4, and 8 h. (B) Proliferation of BMSCs cultured on uncoated and Ta-coated scaffolds at 1, 4, and 7 d. (C) ALP activity of BMSCs cultured on uncoated and Ta-coated scaffolds at 1, 4, and 7 d. All data are expressed as the mean ± SD. *P < 0.05, **P < 0.01.
