Ultra-Low-Cost 3D Bioprinting: Modification and Application of an Off-the-Shelf Desktop 3D-Printer for Biofabrication.

ABSTRACT: 3D bioprinting has become a versatile and powerful method in tissue engineering and regenerative medicine and is increasingly adapted by other disciplines due to its tremendous potential beyond its typical applications. However, commercially available 3D bioprinting systems are typically expensive circumventing the broad implementation, including laboratories in low-resource settings. To address the limitations of conventional and commercially available technology, we developed a 3D bioprinter by modification of an off-the-shelf 3D desktop printer, that can be installed within a single day, is of handy size to fit into a standard laminar flow hood, customizable, ultra-low cost and thus, affordable to a broad range of research labs, or educational institutions. We evaluate accuracy and reproducibility of printing results using alginate and alginate/gelatin-hydrogels and demonstrate its potential for biomedical use by printing of various two-and three-dimensional cell-free and mammalian cell-laden objects using recombinant HEK^YFP cells, stably expressing yellow fluorescent protein (YFP) as a model system and high-content imaging. We further provide a parts list and 3D design files in STL and STEP format for reconstructing the device. A time-lapse video of the custom-built device during operation is available at https://vimeo.com/274482794.

Project description:ObjectiveThis article focused on the application scenarios of three-dimensional (3D) bioprinting and gene-editing technology in various medical fields, including gene therapy, tissue engineering, tumor microenvironment simulation, tumor model construction, cancer regulation and expression, osteogenesis, and skin and vascular regeneration, and summarizing its development prospects and shortcomings.Background3D bioprinting is a process based on additive manufacturing that uses biological materials as the microenvironment living cells. The scaffolds and carriers manufactured by 3D bioprinting technology provide a safe, efficient, and economical platform for genes, cells, and biomolecules. Gene modification refers to replacing, splicing, silencing, editing, controlling or inactivating genes and delivering new genes. The combination of this technology that changes cell function or cell fate or corrects endogenous mutations and 3D bioprinting technology has been widely used in various medical field.MethodsWe conducted a literature search for papers published up to March 2021 on the gene modification combined with 3D bioprinting in various medical fields via PubMed, Web of Science, China National Knowledge Infrastructure (CNKI). The following medical subject heading terms were included for a MEDLINE search: "3D printing/gene editing", "3D printing/genetic modification", "3D printing/seed cell", "bioprinting/gene editing", "bioprinting/genetic modification", "bioprinting/seed cell", "scaffold/gene editing", "scaffold/genetic modification", "scaffold/seed cell", "gene/scaffold", "gene/bioprinting", "gene/3D printing". Quantitative and qualitative data was extracted through interpretation of each article.ConclusionsWe have reviewed the application scenarios of 3D bioprinting and gene-editing technology in various medical fields, it provides an efficient and accurate delivery system for personalized tumor therapy, enhancing the targeting effect while maintaining the integrity of the fabricated structure. It exhibits significant application potential in developing tumor drugs. In addition, scaffolds obtained via 3D bioprinting provide gene therapy applications for skin and bone healing and repair and inducing stem cell differentiation. It also considers the future development direction in this field, such as the emergence and development of gene printing, 4D printing. The combination of nanotechnology and gene printing may provide a new way for future disease research and treatment.
