Scaffold pore size plays a fundamental role in the regeneration of new tissue since it has been shown to direct cell activity in situ. It is well known that cellular response changes in relation with pores diameter. Consequently, researchers developed efficient approaches to realize scaffolds with controllable macro‐, micro‐, and nanoporous architecture. In this context, new strategies aiming at the manufacturing of scaffolds with multiscale pore networks have emerged, in the attempt to mimic the complex hierarchical structures found in living systems. In this review, we aim at providing an overview of the fabrication methods currently adopted to realize scaffolds with controlled, multisized pores highlighting their specific influence on cellular activity.

Pancreatic ductal adenocarcinoma (PDAC) mainly develops in the head of the pancreas, within the acino-ductal unit composed by acinar and ductal cells surrounded by pancreatic stellate cells (PSCs). PSCs strongly...

This project aims at reproducing the morphology and the composition of the pancreatic acino-ductal unit. More specifically, this work involves the use of additive manufacturing technologies to fabricate a 3D exocrine glandular tissue model that mimics in vitro the physiological structure experienced by cells in vivo.
