Fig. 5From: Fabrication and optimization of Nanodiamonds-composited poly(ε-caprolactone) fibrous matrices for potential regeneration of hard tissuesVariation of ALP activities of MC3T3-E1 cultured on the PCL and ND/PCL fibrous matrices (0.5, 1, 2, and 3 wt% ND concentration). The PCL fibrous matrices served as the control. * Significant difference between the two groups (p < 0.05)Back to article page
