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]
Dendrimer and dendron. Dendrimers are highly ordered, branched polymeric molecules. [1] [2] Synonymous terms for dendrimer include arborols and cascade molecules.Typically, dendrimers are symmetric about the core, and often adopt a spherical three-dimensional morphology.
It was noted that as opposed to the flattened morphology typically seen in 2D culture, cells grown on the electrospun fibers exhibited a more rounded 3-dimensional morphology generally observed of tissues in vivo. [17]
Epithelial lingual organoids have been generated using BMI1 expressing epithelial stem cells in three-dimensional culture conditions through the manipulation of EGF, WNT, and TGF-β. [65] This organoid culture, however, lacks taste receptors , as these cells do not arise from Bmi1 expressing epithelial stem cells. [ 65 ]
It was noted that as opposed to the flattened morphology typically seen in 2D culture, cells grown on the electrospun fibers exhibited a more rounded 3-dimensional morphology generally observed of tissues in vivo. [9]
Onymacris unguicularis beetle with landmarks for morphometric analysis. In landmark-based geometric morphometrics, the spatial information missing from traditional morphometrics is contained in the data, because the data are coordinates of landmarks: discrete anatomical loci that are arguably homologous in all individuals in the analysis (i.e. they can be regarded as the "same" point in each ...
This model was limited to the generation of pictures, and is thus bi-dimensional. A similar model to the one described above was subsequently extended to generate three-dimensional structures, and was demonstrated in the video game Minecraft, whose block-based nature made it particularly expedient for the simulation of 3D cellular automatons.

The fourteen three-dimensional lattices, classified by lattice system, are shown above. The crystal structure consists of the same group of atoms, the basis, positioned around each and every lattice point. This group of atoms therefore repeats indefinitely in three dimensions according to the arrangement of one of the Bravais lattices.
