The key goal of tissue engineering within regenerative medicine is to develop strategies aimed at manufacturing viable and functional three-dimensional (3D) constructs incorporating living cells for tissue repair or replacement. Different approaches have been exploited, and this is a research field in constant evolution.¹ 

The general methodology is to utilize 3D scaffolds as temporary supports assisting seeded cells growth, differentiation and new tissue development. These scaffolds may be intended as purely structural supports by providing passive cues to the cells or by incorporating biological cues to actively guide cell and tissue growth.²
