Evaluation of Cartilage Regeneration in Gellan Gum/agar Blended Hydrogel with Improved Injectability

Evaluation of Cartilage Regeneration in Gellan Gum/agar Blended Hydrogel with Improved Injectability Abstract Gellan gum is known to be one of the biocompatible materials that resemble living tissues, continuously delivering stem cells or general cells, and filling voids in the wound. In spite of the many advantages of gellan gum, it has difficulty in the application by inserting the scaffolds into the body. In order to generalize gellan gum for medical purpose, it is necessary to increase the injectability of gellan gum. In this study, gellan gum solutions with 0.2, 0.4, 0.6, 0.8 wt% of agar were prepared. The obtained hydrogels were tested for rheological properties and chondrocytes adhesion, morphology and proliferation. Results showed that the addition of agar, in the starting GG solution, allows extruding the material producing micro-porous scaffolds. The biological evaluation demonstrated that the adhesion and proliferation of chondrocytes increase with the presence of agar in the final structure. The solutions composed of GG and agar represent an efficient, fast and high reproducible methodology with the potential to be used as an injectable hydrogel for cartilage regeneration purposes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Macromolecular Research" Springer Journals

Abstract

Abstract Gellan gum is known to be one of the biocompatible materials that resemble living tissues, continuously delivering stem cells or general cells, and filling voids in the wound. In spite of the many advantages of gellan gum, it has difficulty in the application by inserting the scaffolds into the body. In order to generalize gellan gum for medical purpose, it is necessary to increase the injectability of gellan gum. In this study, gellan gum solutions with 0.2, 0.4, 0.6, 0.8 wt% of agar were prepared. The obtained hydrogels were tested for rheological properties and chondrocytes adhesion, morphology and proliferation. Results showed that the addition of agar, in the starting GG solution, allows extruding the material producing micro-porous scaffolds. The biological evaluation demonstrated that the adhesion and proliferation of chondrocytes increase with the presence of agar in the final structure. The solutions composed of GG and agar represent an efficient, fast and high reproducible methodology with the potential to be used as an injectable hydrogel for cartilage regeneration purposes.
