Figure 3. Cell proliferation on the hydrogels.

Figure 3

(a) hMSC proliferation after 21 days in growth media relative to TCPS mean data (40,458 cells/cm2) demonstrating the effect of sIPN stiffness (102–970 Pa) and RGD adhesive ligand density (0–210 µM). (b) RSM plots demonstrating the effect of sIPN stiffness (102–970 Pa) and bsp-RGD(15) adhesive ligand density (0–210 µM) on hMSC proliferation after 21 days in growth media.
