Cell driven elastomeric particle packing in composite bioinks for engineering and implantation of stable 3D printed structures. Bioact Mater 2025; 44:411-427. [PMID: 39525804 PMCID: PMC11550138 DOI: 10.1016/j.bioactmat.2024.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 10/08/2024] [Accepted: 10/09/2024] [Indexed: 11/16/2024] Open
Abstract
Geometric and structural integrity often deteriorate in 3D printed cell-laden constructs over time due to cellular compaction and hydrogel shrinkage. This study introduces a new approach that synergizes the advantages of cell compatibility of biological hydrogels and mechanical stability of elastomeric polymers for structure fidelity maintenance upon stereolithography and extrusion 3D printing. Enabling this advance is the composite bioink, formulated by integrating elastomeric microparticles from poly(octamethylene maleate (anhydride) citrate) (POMaC) into biologically derived hydrogels (fibrin, gelatin methacryloyl (GelMA), and alginate). The composite bioink enhanced the elasticity and plasticity of the 3D printed constructs, effectively mitigating tissue compaction and swelling. It exhibited a low shear modulus and a rapid crosslinking time, along with a high ultimate compressive strength and resistance to deformation from cellular forces and physical handling; this was attributed to packing and stress dissipation of elastomeric particles, which was confirmed via mathematical modelling. Enhanced functional assembly and stability of human iPSC-derived cardiac tissues and primary vasculature proved the utility of the composite bioink in tissue engineering. In vivo implantation studies revealed that constructs containing POMaC particles exhibited improved resilience against host tissue stress, enhanced angiogenesis, and infiltration of pro-reparative macrophages.

Abstract
Recent advances in medical plastics highlight the need for sustainable materials with desirable elastic properties. Traditional polyester elastomers have been used as alternatives to polyvinyl chloride (PVC) due to their biocompatibility and adjustable mechanical properties. However, these materials often lack the necessary stability and toughness for reliable medical applications. To address these issues, this study introduces renewable 1,12-dodecanedioic acid (DA) to create a copolymer with diols, resulting in a structure akin to polyolefins. This innovative approach significantly enhances toughness by regulating chain segment lengths and integrates high performance with sustainability. The resulting bio-based elastomer exhibits remarkable biocompatibility and elastic recovery (69.0%). This work represents a significant advancement in the development of eco-friendly materials suitable for medical device applications, with potential implications for tissue engineering and other healthcare technologies.

Abstract
Mimicking the curved collagenous fibers in the cardiac extracellular matrix to fabricate elastic scaffolds in vitro is important for cardiac tissue engineering. Here, we developed sinusoidal polycaprolactone (PCL) fibrous scaffolds with commendable flexibility and elasticity to enhance the contractility of primary cardiomyocytes by employing melt-based electrohydrodynamic (EHD) printing. Microscale sinusoidal PCL fibers with an average diameter of ∼10 μm were printed to mimic the collagenous fibers in the cardiac ECM. The sinusoidal PCL fibrous scaffolds were EHD-printed in a layer-by-layer manner and exhibited outstanding flexibility and elasticity compared with the straight ones. The sinusoidal PCL scaffolds provided an elastic microenvironment for the attaching and spreading of primary cardiomyocytes, which facilitated their synchronous contractive activities. Primary cardiomyocytes also showed improved gene expression and maturation on the sinusoidal PCL scaffolds under electrical stimulation for 5 days. It is envisioned that the proposed flexible fibrous scaffold with biomimetic architecture may serve as a suitable patch for tissue regeneration and repair of damaged hearts after myocardial infarction.

Abstract
Biofabrication technologies hold the potential to provide high-throughput, easy-to-operate, and cost-effective systems that recapitulate complexities of the native heart. The size of the fabricated model, printing resolution, biocompatibility, and ease-of-fabrication are some of the major parameters that can be improved to develop more sophisticated cardiac models. Here, we review recent cardiac engineering technologies ranging from microscaled organoids, millimeter-scaled heart-on-a-chip platforms, in vitro ventricle models sized to the fetal heart, larger cardiac patches seeded with billions of cells, and associated biofabrication technologies used to produce these models. Finally, advancements that facilitate model translation are discussed, such as their application as carriers for bioactive components and cells in vivo or their capability for drug testing and disease modeling in vitro.

Abstract
Biodegradable stents are the most promising alternatives for the treatment of cardiovascular disease nowadays, and the strategy of preparing functional coatings on the surface is highly anticipated for addressing adverse effects such as in-stent restenosis and stent thrombosis. Yet, inadequate mechanical stability and biomultifunctionality limit their clinical application. In this study, we developed a multicross-linking hydrogel on the polylactic acid substrates by dip coating that boasts impressive antithrombotic ability, antibacterial capability, mechanical stability, and self-healing ability. Gelatin methacryloyl, carboxymethyl chitosan, and oxidized sodium alginate construct a double-cross-linking hydrogel through the dynamic Schiff base chemical and in situ blue initiation reaction. Inspired by the adhesion mechanism employed by mussels, a triple-cross-linked hydrogel is formed with the addition of tannic acid to increase the adhesion and antibiofouling properties. The strength and hydrophilicity of hydrogel coating are regulated by changing the composition ratio and cross-linking degree. It has been demonstrated in tests in vitro that the hydrogel coating significantly reduces the adhesion of proteins, MC3T3-E1 cells, platelets, and bacteria by 85% and minimizes the formation of blood clots. The hydrogel coating also exhibits excellent antimicrobial in vitro and antiinflammatory properties in vivo, indicating its potential value in vascular intervention and other biomedical fields.

Abstract
Stem cells are undifferentiated cells presenting extensive self-renewal features and the ability to differentiate "in vitro" and "in vivo" into a range of lineage cells, like chondrogenic, osteogenic and adipogenic lineages when cultured in specific inducing media. Two major domains of clinical applications of stem cells in thoracic surgery have been investigated: regenerative medicine, which is a section of translational research in tissue engineering focusing on the replacement, renewal or regeneration of cells, tissues and organs to re-establish damaged physiologic functions; drug loading and delivery, representing a new branch proposing stem cells as carriers to provide selected districts with anti-cancer agents for targeted treatments.
