Dear Colleagues

Generating functional tissue models that mimic aspects of cell 3D microenvironments is challenging. This may be addressed by combining 3D bioprinting of bioinspired biomaterials and microfluidic technology to develop organ-on-chip models. The hierarchical structure and complicated self-regeneration of complex tissues make difficult the engineering of platforms that mimic tissue microstructure-function relationship in vitro. The 3D bioprinting of hybrid tissue models is an emerging and powerful technology to achieve the biofabrication of tissue and organ models.

This special issue is oriented to all types of design and characterization of 3D bioprinting and organ-on-chip platforms, with printed tissue models and/or miniaturized microfluidics, to approach biological and physiological parameters of the in vivo tissue counterparts. Special attention will be given but will not be limited to the development of biocompatible hydrogel polymer bio-inks and microsystems engineering setups to achieve relevant functional tissues, by having understanding on material science and technological applications.
