Tissue-on-chip (TOC) systems aim at replicating complex biological dynamics in vitro with the potential either to improve the understanding of human biology or to develop more accurate therapeutic strategies. To replicate faithfully the intricate interrelationships between cells and their surrounding microenvironment, the three-dimensional (3D) tissue model must possess a responsive extracellular matrix (ECM). ECM remodeling plays a pivotal role in guiding cells and tissues functions and such aspect is somewhat denied during in vitro studies. For this purpose, we fabricated a micro-perfusion bioreactor capable to sustain the viability of 3D engineered tissue models recapitulating the process of the native ECM deposition and assembly. Engineered human dermis micro-tissue precursors (HD-μTP) were used as building blocks to generate a final tissue. HD-μTP were loaded in the perfusion space of the micro …
