Figure 7. Quantification of biochemical soluble factors and proteins according to nanotopographical density.

Figure 7

Quantification of (A) BMP-2 and (B) VEGF protein in conditioned medium of hMSCs on the nanogrooved matrices and flat substrate for 21 days. The results indicate no significant difference between the nanotopography and flat (P > 0.05). (C) Western blot analysis and (D) quantification of the values of integrin β1 and N-cadherin expression of hMSCs cultured on nanogrooved matrices and flat substrate. The hMSCs were cultured for 7 days and the western blot study was performed under same experimental conditions.
