It has also been employed in various advanced industrial areas. The development of intelligent biomedical engineering has raised the requirements for 3D printing, such as flexible manufacturing processes and technologies, biocompatible constituents, and alternative bioproducts. However, state-of-the-art 3D printing mainly involves inorganics or polymers and generally focuses on traditional industrial fields, thus severely limiting applications demanding biocompatibility and biodegradability. In this regard, peptide architectonics, which are self-assembled by programmed amino acid sequences that can be flexibly functionalized, have shown promising potential as bioinspired inks for 3D printing. Therefore, the combination of 3D printing and peptide self-assembly potentially opens up an alternative avenue of 3D bioprinting for diverse advanced applications. Israel, a small but innovative nation, has significantly contributed to 3D bioprinting in terms of scientific studies, marketization, and peptide architectonics, including modulations and applications, and ranks as a leading area in the 3D bioprinting field. This review summarizes the recent progress in 3D bioprinting in Israel, focusing on scientific studies on printable components, soft devices, and tissue engineering. This paper further delves into the manufacture of industrial products, such as artificial meats and bioinspired supramolecular architectures, and the mechanisms, physicochemical properties, and applications of peptide self-assembly. Undoubtedly, Israel contributes significantly to the field of 3D bioprinting and should thus be appropriately recognized.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140809288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cells are the fundamental building blocks of tissues. Compared with traditional two-dimensional cultured cells, cell spheres are three-dimensional (3D) structures that can naturally form complex cell–cell and cell–matrix interactions. This structure is close to the natural environment of cells in living organisms. In addition to being used in disease modeling and drug screening, spheroids have significant potential in tissue regeneration. The 3D bioprinting is an advanced biofabrication technique. It accurately deposits bioinks into predesigned 3D shapes to create complex tissue structures. Although 3D bioprinting is efficient, the time required for cells to develop into complex tissue structures can be lengthy. The 3D bioprinting of spheroids significantly reduces the time required for their development into large tissues/organs during later cultivation stages by printing them with high cell density. Combining spheroid fabrication and bioprinting technology should provide a new solution to many problems in regenerative medicine. This paper systematically elaborates and analyzes the spheroid fabrication methods and 3D bioprinting strategies by introducing spheroids as building blocks.

However, the lack of tumor models able to precisely emulate natural brain tumor tissue has impeded the study of the effects of hypoxia on the progression and growth of tumor cells. This study reports a three-dimensional (3D) brain tumor model obtained by encapsulating U87MG (U87) cells in a hydrogel containing type I collagen. It also documents the effect of various oxygen concentrations (1%, 7%, and 21%) in the culture environment on U87 cell morphology, proliferation, viability, cell cycle, apoptosis rate, and migration. Finally, it compares two-dimensional (2D) and 3D cultures. For comparison purposes, cells cultured in flat culture dishes were used as the control (2D model). Cells cultured in the 3D model proliferated more slowly but had a higher apoptosis rate and proportion of cells in the resting phase (G0 phase)/gap I phase (G1 phase) than those cultured in the 2D model. Besides, the two models yielded significantly different cell morphologies. Finally, hypoxia (e.g., 1% O<sub>2</sub>) affected cell morphology, slowed cell growth, reduced cell viability, and increased the apoptosis rate in the 3D model. These results indicate that the constructed 3D model is effective for investigating the effects of biological and chemical factors on cell morphology and function, and can be more representative of the tumor microenvironment than 2D culture systems. The developed 3D glioblastoma tumor model is equally applicable to other studies in pharmacology and pathology.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140591571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These tissue-engineered structures are intended to integrate with the patient’s body. Vascular tissue engineering (TE) is relevant in TE because it supports the sustained oxygenization and nutrition of all tissue-engineered constructs. Bioinks have a specific role, representing the necessary medium for printability and vascular cell growth. This review aims to understand the requirements for the design of vascular bioinks. First, an in-depth analysis of vascular cell interaction with their native environment must be gained. A physiological bioink suitable for a tissue-engineered vascular graft (TEVG) must not only ensure good printability but also induce cells to behave like in a native vascular vessel, including self-regenerative and growth functions. This review describes the general structure of vascular walls with wall-specific cell and extracellular matrix (ECM) components and biomechanical properties and functions. Furthermore, the physiological role of vascular ECM components for their interaction with vascular cells and the mode of interaction is introduced. Diverse currently available or imaginable bioinks are described from physiological matrix proteins to nonphysiologically occurring but natural chemical compounds useful for vascular bioprinting. The physiological performance of these bioinks is evaluated with regard to biomechanical properties postprinting, with a view to current animal studies of 3D printed vascular structures. Finally, the main challenges for further bioink development, suitable bioink components to create a self-assembly bioink concept, and future bioprinting strategies are outlined.

However, they fail to provide long-term clinical resolution, necessitating a functional biomimetic tissue engineering alternative. The use of native human bone tissue for synthesizing a biomimetic material ink for three-dimensional (3D) bioprinting of skeletal tissue is an attractive strategy for tissue regeneration. Thus, human bone extracellular matrix (bone-ECM) offers an exciting potential for the development of an appropriate microenvironment for human bone marrow stromal cells (HBMSCs) to proliferate and differentiate along the osteogenic lineage. In this study, we engineered a novel material ink (LAB) by blending human bone-ECM (B) with nanoclay (L, Laponite<sup>®</sup>) and alginate (A) polymers using extrusion-based deposition. The inclusion of the nanofiller and polymeric material increased the rheology, printability, and drug retention properties and, critically, the preservation of HBMSCs viability upon printing. The composite of human bone-ECM-based 3D constructs containing vascular endothelial growth factor (VEGF) enhanced vascularization after implantation in an ex vivo chick chorioallantoic membrane (CAM) model. The inclusion of bone morphogenetic protein-2 (BMP-2) with the HBMSCs further enhanced vascularization and mineralization after only seven days. This study demonstrates the synergistic combination of nanoclay with biomimetic materials (alginate and bone-ECM) to support the formation of osteogenic tissue both in vitro and ex vivo and offers a promising novel 3D bioprinting approach to personalized skeletal tissue repair.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140035598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional screws are mechanically fixed with thread and often face long-term failure due to poor osseointegration. To improve osseointegration, screws are evolving from solid and smooth to porous and rough. Additive manufacturing (AM) offers a high degree of manufacturing freedom, enabling the preparation of predesigned screws that are porous and rough. This paper provides an overview of the problems currently faced by bone screws: long-term loosening and screw breakage. Next, advances in osseointegrated screws are summarized hierarchically (sub-micro, micro, and macro). At the sub-microscale level, we describe surface-modification techniques for enhancing osseointegration. At the micro level, we summarize the micro-design parameters that affect the mechanical and biological properties of porous osseointegrated screws, including porosity, pore size, and pore shape. In addition, we highlight three promising pore shapes: triply periodic minimal surface, auxetic structure with negative Poisson ratio, and the Voronoi structure. At the macro level, we outline the strategies of graded design, gradient design, and topology optimization design to improve the mechanical strength of porous osseointegrated screws. Simultaneously, this paper outlines advances in AM technology for enhancing the mechanical properties of porous osseointegrated screws. AM osseointegrated screws with hierarchical design are expected to provide excellent long-term fixation and the required mechanical strength.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140007973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
