Fig. 7From: Facile distribution of an alkaline microenvironment improves human bone marrow mesenchymal stem cell osteogenesis on a titanium surface through the ITG/FAK/ALP pathwayFluorescence microscopy images of live/dead staining of BMSCs cultured on SLA surfaces (a) and SLA discs treated with 20 mM (b), 50 mM (c), 100 mM (d), or 200 mM (e) sodium bicarbonate after 72 h of cell seeding. Proliferation of BMSCs cultured in each group for 1, 3, 5, and 7 days determined by CCK-8 assays (f). Data are presented as the mean ± standard deviation (n = 3, *P < 0.05; **P < 0.01; ***P < 0.001)Back to article page
