Abstract Bioprinting of cellular aggregates, such as tissue spheroids, to form three-dimensional (3D) complex-shaped arrangements, has posed a major challenge due lack robust, reproducible and practical bioprinting techniques. Here, we demonstrate 3D aspiration-assisted freeform spheroids by precisely positioning them in self-healing yield-stress gels, enabling the self-assembly for fabrication tissues. The presented approach enables traverse directly from cell media gel on demand. We study...
Aspiration-assisted freeform bioprinting (AAfB) has emerged as a promising technique for precise placement of tissue spheroids in three-dimensional (3D) space enabling fabrication. To achieve success embedded using AAfB, an ideal support bath should possess shear-thinning behavior and yield-stress to facilitate tight fusion assembly bioprinted forming tissues. Several studies have demonstrated baths the past few years, yet majority these materials poses challenges due their low...
Abstract Current nucleic acid delivery methods have not achieved efficient, non‐toxic of miRNAs with tumor‐specific selectivity. In this study, a new system based on light‐inducible gold–silver–gold, core–shell–shell (CSS) nanoparticles is presented. This delivers small therapeutics precise spatiotemporal control, demonstrating the potential for achieving selectivity and efficient miRNA mimics. The particles leverage photothermal heating metal due to local surface plasmonic resonance...
Despite substantial advancements in development of cancer treatments, lack standardized and physiologically-relevant vitro testing platforms limit the early screening anticancer agents. A major barrier is complex interplay between tumor microenvironment immune response. To tackle this, a dynamic-flow based 3D bioprinted multi-scale vascularized breast model, responding to chemo immunotherapeutics developed. Heterotypic tumors are precisely at pre-defined distances from perfused vasculature,...
Abstract The gut microbiota influences systemic immunity and the function of distal tissues, including brain, liver, skin, lung, muscle. However, role in foreign body response (FBR) fibrosis around medical implants is largely unexplored. To investigate this connection, we perturbed homeostasis murine via enterotoxigenic Bacteroides fragilis (ETBF) infection implanted synthetic polymer polycaprolactone (PCL) into a muscle injury. ETBF mice led to increased neutrophil γδ T cell infiltration...
Abstract The engineering of osteochondral interfaces remains a challenge. MicroRNAs (miRs) have emerged as significant tools to regulate the differentiation and proliferation osteogenic chondrogenic formation in human musculoskeletal system. Here, we describe novel approach reconstruction based on three-dimensional (3D) bioprinting miR-transfected adipose-derived stem cell (ADSC) spheroids produce heterotypic interface that addresses intrinsic limitations traditional inducing zonal via use...
Tissue biofabrication that replicates an organ-specific architecture and function requires physiologically-relevant cell densities. Bioprinting using spheroids has the potential to create constructs with native densities, but its application is limited due lack of practical, scalable techniques. This study presents HITS-Bio (High-throughput Integrated Fabrication System for Bioprinting), a novel multiarray spheroid bioprinting technology enabling tissue fabrication by rapidly positioning...

Engineered bone grafts require a vascular network to supply cells with oxygen, nutrients and remove waste. Using heterotypic mature create these in vivo has resulted limited cell density, ectopic tissue formation disorganized tissue. Despite evidence that progenitor aggregates, such as spheroids, are potential candidate for fabrication of native-like pre-vascularized tissue, the factors dictating co-differentiation remains poorly understood. In this study, we examined three-dimensional...
