A 3D cell culture is an artificially created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions. Unlike 2D environments (e.g. a Petri dish), a 3D cell culture allows cells in vitro to grow in all directions, similar to how they would in vivo. [1]
Currently, there is an increase in use of 3D cell cultures in research areas including drug discovery, cancer biology, regenerative medicine, nanomaterials assessment and basic life science research. [66] [67] [68] 3D cell cultures can be grown using a scaffold or matrix, or in a scaffold-free manner. Scaffold based cultures utilize an ...
3D cell culture methods have been developed to enable research into the behavior of cells in an environment that represents their interactions in-vivo more accurately [5].. 3D cell culturing by magnetic levitation uses biocompatible polymer-based reagents [2] to deliver magnetic nanoparticles to individual cells, so that an applied magnetic driver can levitate cells off the bottom of the cell ...
3D cell-culture models exceed 2D culture systems by promoting higher levels of cell differentiation and tissue organization. 3D culture systems are more successful because the flexibility of the ECM gels accommodates shape changes and cell-cell connections – formerly prohibited by rigid 2D culture substrates.
Left: multicellular hollow spheres of cells, termed acini, were grown in 3D culture. Right: after 2 days of treatment with HGF cells have formed multiple branches. In the last 20 years, understanding of MDCK cell biology in 3D culture has been advanced most notably by the laboratory of Keith Mostov. This group has focused on the regulation of ...
Another open multi-culture device fabricated by razor-printing is capable of integrating numerous culture modalities, including 2D, 3D, Transwell, and spheroid culture. [49] It also shows improved diffusion to promote soluble factor paracrine signaling. [49]
