Abstract

Abstract : Tissue engineering/regenerative medicine (TERM) is an interdisciplinary field that applies the principle of engineering and life sciences to restore/replace damaged tissues/organs with in vitro artificially‐created ones. Research on TERM quickly moves forward. Today newest technologies and discoveries, such as 3D‐/bio‐printing, allow in vitro fabrication of ex‐novo made tissues/organs, opening the door to wide and probably never‐ending application possibilities, from organ transplant to drug discovery, high content screening and replacement of laboratory animals. Imaging techniques are fundamental tools for the characterization of tissue engineering (TE) products at any stage, from biomaterial/scaffold to construct/organ analysis. Indeed, tissue engineers need versatile imaging methods capable of monitoring not only morphological but also functional and molecular features, allowing three‐dimensional (3D) and time‐lapse in vivo analysis, in a non‐destructive, quantitative, multidimensional analysis of TE constructs, to analyze their pre‐implantation quality assessment and their fate after implantation. This review focuses on the newest developments in imaging technologies and applications in the context of requirements of the different steps of the TERM field, describing strengths and weaknesses of the current imaging approaches.
