Abstract

In this study, 3D hydrogel-based vascular structures with multilevel fluidic channels (macro-channel for mechanical stimulation and microchannel for nutrient delivery and chemical stimulation) were fabricated by extrusion-based three-dimensional (3D) bioprinting, which could be integrated into organ-on-chip devices that would better simulate the microenvironment of blood vessels. In this approach, partially cross-linked hollow alginate filaments loading fibroblasts and smooth muscle cells were extruded through a coaxial nozzle and then printed along a rotated rod template, and endothelial cells were seeded into the inner wall. Because of the fusion of adjacent hollow filaments, two-level fluidic channels, including a macro-channel in the middle formed from the cylindrical template and a microchannel around the wall resulted from the hollow filaments were formed. By this method, different shapes of vessellike structures of millimeter diameter were printed. The structures printed using 4% alginate exhibited ultimate strength of 0.184 MPa, and L929 mouse fibroblasts encapsulated in the structures showed over 90% survival within 1 week. As a proof of concept, an envisioned load system of both mechanical and chemical stimulation was demonstrated. In addition, a vascular circulation flow system, a cerebral artery surgery simulator, and a cell coculture model were fabricated to demonstrate potential tissue engineering applications of these printed structures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
