| Outline of Final Research Achievements |
In this investigation, we used Methylcellulose (MC) to develop and optimize a novel scaffold material for bone cell transplantation. A series of MC scaffolds with different porosity, cross-link density, and size were fabricated. Results showed that Sodium Chloride (NaCl) has a great effect on the homogeneity and porosity of the scaffold in a dose-dependent manner. Crosslinking using carbonyldiimidazole (CDI) at different concentrations showed no significant changes in the scaffold’s characteristics. As a result of the lyophilization procedure, the thickness of the scaffold was significantly reduced; consequently, affecting the scaffold's structure and compromising the mechanical strength needed for tissue transplantation. Although the production of MC scaffolds was achieved, homogeneity between samples was rather difficult to obtain. Thus, further optimization is required for the production of viable cell transplantation scaffolds using methylcellulose.

| Academic Significance and Societal Importance of the Research Achievements |
Increase in the life expectancy and diseases that causes bone loss, has shown an urgent need to improve and optimize bone graft treatment. Development of novel regenerative biomaterials such as Methylcellulose scaffolds, aims to improve our knowledge on the intrinsic mechanism of tissue repair.
