FIG. 7. — Methacrylated hyaluronic acid (HA) compared with polyethylene glycol (PEG). Modulus of acellular HA and PEG hydrogels (A), live (green)/dead (red) images of mesenchymal stem cell–laden hydrogels at 1 and 24 h after polymerization; scale bar = 200 μm (B), relative mitochondrial activity for HA (black) and PEG (white) hydrogels after 7 and 14 days of in vitro culture (C). There were no statistical differences in hydrogel moduli and viability between the HA and PEG groups. Color images available online at www.liebertonline.com/ten.
