Hyaluronic Acid Based Hydrogels for Regenerative Medicine Applications

Figure 10

Stem cell differentiation expressed as the ratio between the quantity of ALP and the quantity of DNA; after that the cells were placed in contact with the hydrogels for 7, 14, and 21 days in the presence of osteogenic medium; the hydrogels are characterized by different HA concentrations (5% and 6%) and different HA/DVS weight ratio (2.5 : 1, 5 : 1, and 8 : 1).
