Fig. 5From: Evaluation of Alginate and Hyaluronic Acid for Their Use in Bone Tissue EngineeringAlkaline phosphatase (ALP) activity in MC3T3-E1 cells cultured for 21 days with alginate or hyaluronic acid at different polymer concentrations (1, 2 and 3 %). Values represent the mean ± SEM. Significant differences were assessed by Student t test: p < 0.05 a versus control PBS, b alginate versus HA, c between polymer concentrationsBack to article page
