Influence of gelatin modification on enzymatically-gellable pectin-gelatin hydrogel properties for soft tissue engineering applications
Injectable in situ-forming hydrogels appears to be a promising approach for tissue engineering applications. In this study, the effect of phenol moiety (Ph) addition to gelatin in enzymatically-gellable modified pectin hydrogel (Pec-Ph) was studied. Addition of gelatin-Ph to Pec-Ph (Pec-Ph/Gel-Ph) altered the physical properties of Pec-Ph-based hydrogels as compared to unmodified gelatin (Pec-Ph/Gel) addition. Swelling ratio and degradation rates of the Pec-Ph/Gel-Ph hydrogel decreased 35% and 50%, respectively, and the elasticity of Pec-Ph/Gel-Ph hydrogel was higher than the Pec-Ph/Gel hydrogels. Scanning electron microscopy images showed that the existence of phenolic groups in gelatin decreased the pore size of Pec-Ph/Gel-Ph hydrogels. Culture of chondrocyte cells in the Pec-Ph/Gel-Ph hydrogels showed more metabolic activity (4×) during a 14-day culture period. Hydrogels subcutaneously implanted in rats could also be identified readily without complete absorption and signs of toxicity or any untoward reactions after 1 month. The work showed the potential of Pec-Ph/Gel-Ph hydrogels as a promising in situ injectable hydrogel for soft tissue engineering applications.
