Fabrication of 3D PCL/PVP scaffolds using monosodium glutamate as porogen by solvent casting/particulate leaching method for oral and maxillofacial bone tissue engineering.

The design of three-dimensional (3D) scaffolds should focus on creating highly porous, 3D structures with an interconnected pore network that supports cell growth. The scaffold's pore interconnectivity is directly linked to vascularization, cell seeding, guided cell migration, and transportation of nutrients and metabolic waste. In this study, different types of food flavors including monosodium glutamate, sugar, and sodium chloride were used as the porogens along with PCL/PVP blend polymer for solvent casting/particulate leaching method.
