Optimization of chaotic bioprinting to produce reinforced multichannel hydrogel fibers for the maturation of skeletal muscle tissue under agitation
(Universidad de Ingeniería y TecnologíaPE, 2024)
Chaotic bioprinting enables the fabrication of microstructured hydrogel fibers with co-extruding permanent and fugitive inks using a kenics static mixer (KSM) printhead. However, these fibers degrade completely after 7 ...
14-3-3ε protein-loaded 3D hydrogels favor osteogenesis
(Springer, 2020-11)
3D printing has emerged as vanguard technique of biofabrication to assemble cells, biomaterials and biomolecules in a spatially controlled manner to reproduce native tissues. In this work, gelatin methacrylate (GelMA)/alginate ...
Chaotic bioprinting of skeletal muscle-like tissues
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-12-02)
Skeletal muscle diseases affect around 1.7 billion people worldwide, leading to pain and disability. Although conventional treatments, such as, autologous or exogenous grafts have benefited many patients, they still exhibit ...
Desenvolvimento e implementação de bioimpressora 3D para engenharia de tecidos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia BiomédicaUTFPR, 2020-07-30)
The principle of a 3D printer is the opposite of subtractive manufacturing, as is the case with a CNC, in which manufacturing is based on removing material to shape an object. 3D printing is a manufacturing method with the ...
Development of a GelMA-based bioink enhanced with minimally-processed tissue for the fabrication of skeletal muscle
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-06-12)
Bioprinting, an emerging technology that uses living cells and biomaterials for fabricating engineered tissues with complex three-dimensional (3D) architecture, has become popular as an alternative to conventional 3D-culture ...

(Universidade Federal de São Paulo, 2022-07-11)
A abrangência da aplicação da impressão tridimensional aliada ao potencial de
otimização oferecido pela tecnologia tem estabelecido um papel essencial para esta
no futuro da indústria. Isto deve-se à sua capacidade de ...
Biofabricação de scaffolds com fosfatos de cálcio e interconectividade estruturada entre poros
(Universidade Estadual Paulista (Unesp), 2019-08-21)
Há décadas, a engenharia de tecidos passou a ser considerada em diversas aplicações, um tratamento médico adequado, devido suas excelentes vantagens, além da escassez de órgãos e disponibilidade de tecidos para serem ...
Fabrication and characterization of glass micropipettes: Exploration of use as single-cell manipulation and bioprinting tips
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-12-06)
Micropipettes are primarily used for cell transfection procedures (microinjection). However, their use has been limited to cells larger than 25 µm in diameter. Alternatively, nanopipettes have been shown to enable the ...
The significance of biomacromolecule alginate for the 3D printing of hydrogels for biomedical applications
(2022-07-01)
Natural biopolymers have been widely employed as biomaterial ink hydrogels for three-dimensional (3D) extrusion bioprinting in the preparation of the next generation of bioengineering materials for healthcare applications. ...
