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]
[20] [21] Microfluidic BBB in vitro models replicate a 3D environment for embedded cells (which provides precise control of cellular and extracellular environment), replicate shear stress, have more physiologically relevant morphology in comparison to 2D models, and provide easy incorporation of different cell types into the device.

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 ...
Organ culture is the cultivation of either whole organs or parts of organs in vitro. [1] It is a development from tissue culture methods of research, as the use of the actual in vitro organ itself allows for more accurate modelling of the functions of an organ in various states and conditions.
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]
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 ...
A scientific model seeks to represent empirical objects, phenomena, and physical processes in a logical and objective way. All models are in simulacra, that is, simplified reflections of reality that, despite being approximations, can be extremely useful. [6] Building and disputing models is fundamental to the scientific enterprise.
They function similarly to other 3D bioprinting processes but are optimized for zero gravity settings. Limitations of microgravity bioprinting are shared amongst other 3D bioprinting techniques. [7] An added challenge is sending biomaterials and bioinks to space when the supply on board the ISS has been extinguished.
