Abstract Multi‐cellular spheroids are formed as a 3D structure with dense cell–cell/cell–extracellular matrix interactions, and thus, have been widely utilized implantable therapeutics various ex vivo tissue models in engineering. In principle, spheroid culture methods maximize cell–cell cohesion induce spontaneous cellular assembly while minimizing interactions substrates by using physical forces such gravitational or centrifugal forces, protein‐repellant biomaterials, micro‐structured surfaces. addition, biofunctional materials including magnetic nanoparticles, polymer microspheres, nanofiber particles combined cells to harvest composite spheroids, accelerate formation, increase the mechanical properties viability of direct differentiation stem into desirable cell types. Biocompatible hydrogels developed produce microgels for fabrication size‐controlled high efficiency. Recently, further engineered fabricate structurally functionally reliable vitro artificial tissues desired shape enhanced specific biological functions.

Abstract Highly vascularized complex liver tissue is generally divided into lobes, lobules, hepatocytes, and sinusoids, which can be viewed under different types of lens from the micro‐ to macro‐scale. To engineer multiscaled heterogeneous tissues, a sophisticated rapid engineering approach required, such as advanced 3D bioprinting. In this study, preset extrusion bioprinting technique, create heterogeneous, multicellular, multimaterial structures simultaneously, utilized for creating hepatic lobule (≈1 mm) array. The fabricated lobules include cells, endothelial lumen. cells surround exterior lumen, finally, become interconnected with each other. Compared cell/endothelial cell mixtures, shows higher albumin secretion, urea production, albumin, MRP2, CD31 protein levels, well as, cytochrome P450 enzyme activity. It found that type spatial patterning in bioink accelerates cellular organization, could preserve structural integrity improve functions. conclusion, extruded within highly construct are successfully constructed, enabling both macro‐scale fabrication, support creation large constructs multiscale engineering.

Abstract Nonclinical testing has served as a foundation for evaluating potential risks and effectiveness of investigational new drugs in humans. However, the current two‐dimensional (2D) vitro cell culture systems cannot accurately depict simulate rich environment complex processes observed vivo, whereas animal studies present significant drawbacks with inherited species‐specific differences low throughput increased demands. To improve nonclinical prediction drug safety efficacy, researchers continue to develop novel models evaluate promote use improved cell‐ organ‐based assays more accurate representation human susceptibility response.
