Freeform inkjet printing of cellular structures with bifurcations

Abstract

Organ printing offers a great potential for the freeform layer‐by‐layer fabrication of three‐dimensional (3D) living organs using cellular spheroids or bioinks as building blocks. Vascularization is often identified as a main technological barrier for building 3D organs. As such, the fabrication of 3D biological vascular trees is of great importance for the overall feasibility of the envisioned organ printing approach. In this study, vascular‐like cellular structures are fabricated using a liquid support‐based inkjet printing approach, which utilizes a calcium chloride solution as both a cross‐linking agent and support material. This solution enables the freeform printing of spanning and overhang features by providing a buoyant force. A heuristic approach is implemented to compensate for the axially‐varying deformation of horizontal tubular structures to achieve a uniform diameter along their axial directions. Vascular‐like structures with both horizontal and vertical bifurcations have been successfully printed from sodium alginate only as well as mouse fibroblast‐based alginate bioinks. The post‐printing fibroblast cell viability of printed cellular tubes was found to be above 90% even after a 24 h incubation, considering the control effect. Biotechnol.

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.
