From: Evaluation of Alginate and Hyaluronic Acid for Their Use in Bone Tissue Engineering
Expression of osteoblast differentiation related genes in MC3T3-E1 cells cultured for 21 days with alginate or hyaluronic acid at different polymer concentrations (2 and 3 %). Data represent relative mRNA levels of target genes normalized with reference genes, expressed as a percentage of untreated cells (PBS), which were set to 100 %. Values represent the mean ± SEM. Differences between groups were assessed by Student t test: p < 0.05 a versus control PBS, b alginate versus HA, c between polymer concentrations
