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]
Examples are the establishment of an in vitro model for intestinal Shigella flexneri infection using the Emulate intestine-on-a-chip system or the recreation of a complex faeces-derived microbiota population with both aerobic and anaerobic species.
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
In vitro (meaning in glass, or in the glass) studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called " test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes , and microtiter ...
Since 2014, the PDB format was substituted as the standard PDB archive distribution by the PDBx/mmCIF file format (.cif). While PDB format contains a set of records identified by a keyword of up to six characters, the PDBx/mmCIF format uses a structure based on key and value, where the key is a name that identifies some feature and the value is ...
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate.
Recent advances in cell repellent microtiter plates has allowed rapid, cost-effective screening of large small molecule drug like libraries against 3D models of pancreas cancer. These models are consistent in phenotype and expression profiles with those found in the lab of Dr. David Tuveson. Epithelial organoid [15] [80] Lung organoid [81]
Stem-cell in-vitro Stem cells could be used as an ideal in vitro platform to study developmental changes at the molecular level. Neural stem cells (NSC) for examples have been used as a model to study the mechanisms behind the differentiation and maturation of cells of the central nervous system (CNS).
