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]
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 ...
There are a variety of platforms used to facilitate the growth of three-dimensional cellular structures including scaffold systems such as hydrogel matrices [70] and solid scaffolds, and scaffold-free systems such as low-adhesion plates, nanoparticle facilitated magnetic levitation, [71] hanging drop plates, [72] [73] and rotary cell culture ...
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
Blood vessels have been observed to grow through the scaffold, thus the scaffold and cells are being integrated into the host tissue. A combination of engineered scaffolds presents an option for a 3D scaffold that can have both the necessary patterns for cell adhesion and the flexibility to adapt to the ever changing environment at the injury site.
Nano-scaffolding or nanoscaffolding is a medical process used to regrow tissue and bone, including limbs and organs. The nano-scaffold is a three-dimensional structure composed of polymer fibers very small that are scaled from a Nanometer (10 −9 m) scale. [1]
