Emerging biofabrication approaches for gastrointestinal organoids towards patient specific cancer models

Fernando Soto et al. Cancer Lett. .

Abstract

Tissue engineered organoids are simple biomodels that can emulate the structural and functional complexity of specific organs. Here, we review developments in three-dimensional (3D) artificial cell constructs to model gastrointestinal dynamics towards cancer diagnosis. We describe bottom-up approaches to fabricate close-packed cell aggregates, from the use of biochemical and physical cues to guide the self-assembly of organoids, to the use of engineering approaches, including 3D printing/additive manufacturing and external field-driven protocols. Finally, we outline the main challenges and possible risks regarding the potential translation of gastrointestinal organoids from laboratory settings to patient-specific models in clinical applications.

Keywords: Bioengineering; Externally driven assembly; Organ on a chip; Personalized medicine; Self-assembly.
