A stereolithography-based bioprinting platform for multimaterial fabrication of heterogeneous hydrogel constructs is presented. Dynamic patterning by a digital micromirror device, synchronized moving stage and microfluidic device containing four on/off pneumatic valves, used to create 3D constructs. The novel capable fast switching between different (cell-loaded) bioinks, achieve layer-by-layer bioprinting. Compared conventional bioprinters, the system provides unique advantage capability at...
The development of a multimaterial extrusion bioprinting platform is reported. This capable depositing multiple coded bioinks in continuous manner with fast and smooth switching among different reservoirs for rapid fabrication complex constructs, through digitally controlled from single printhead consisting bundled capillaries synergized programmed movement the motorized stage.
3D bioprinting technology provides programmable and customizable platforms to engineer cell-laden constructs mimicking human tissues for a wide range of biomedical applications. However, the encapsulated cells are often restricted in spreading proliferation by dense biomaterial networks from gelation bioinks. Herein, cell-benign approach is reported directly bioprint porous-structured hydrogel using an aqueous two-phase emulsion bioink. The bioink, which contains two immiscible phases...
Bioinks with shear-thinning/rapid solidification properties and strong mechanics are usually needed for the bioprinting of three-dimensional (3D) cell-laden constructs. As such, it remains challenging to generate soft constructs from bioinks at low concentrations that favorable cellular activities. Herein, we report a strategy fabricate tunable 3D microenvironments achieved by gelatin methacryloyl (GelMA)/alginate core/sheath microfibers, where alginate sheath serves as template support...
Pathologic thrombosis kills more people than cancer and trauma combined; it is associated with significant disability morbidity, represents a major healthcare burden. Despite advancements in medical therapies imaging, there often incomplete resolution of the thrombus. The residual thrombus can undergo fibrotic changes over time through infiltration fibroblasts from surrounding tissues eventually transform into permanent clot post-thrombotic syndrome. In order to understand importance...
Recent advancements in bioprinting techniques have enabled convenient fabrication of micro-tissues organ-on-a-chip platforms. In a sense, the success bioprinted depends on how close their architectures are to anatomical features native counterparts. The resolution largely relates technical specifications bioprinter platforms and physicochemical properties bioinks. this article, we compare inkjet, extrusion, light-assisted technologies for towards construction biomimetic Our theoretical...
Recent advancements in digital-light-processing (DLP)-based bioprinting and hydrogel engineering have enabled novel developments organs-on-chips. In this work, we designed developed a multi-material, DLP-based bioprinter for rapid, one-step prototyping of hydrogel-based microfluidic chips. A composite bioink based on poly-ethylene-glycol-diacrylate (PEGDA) gelatin methacryloyl (GelMA) was optimized through varying the parameters such as light exposure time, composition, layer thickness. We...
Cardiac tissue is characterized by being dynamic and contractile, imparting the important role of biomechanical cues in regulation normal physiological activity or pathological remodeling. However, mechanical tension ability also varies due to extracellular matrix remodeling fibrosis, accompanied with phenotypic transition from cardiac fibroblasts (CFs) myofibroblasts. It hypothesized that regulates within fibrosis a strain-mediated manner. In this study, microdevice able simultaneously...
