The animal extracellular matrix includes the interstitial matrix and the basement membrane. [7] Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM. [8]
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]
As the natural extracellular matrix (ECM) is important in the survival, proliferation, differentiation and migration of the cells, hydrogels mimicking natural ECM structure are considered as potential approaches towards in vivo –like cell culturing. [2] [3] GrowDex is NFC hydrogel for 3D cell culture commercialized by UPM, Finland. [4]
This act initiates cell-cell interactions in the absence of any artificial surface or matrix. Magnetic fields are designed to form 3D multicellular structures, including the expression of extracellular matrix proteins. The matrix, protein expression, and response to exogenous agents of the resulting tissue show similarity to in-vivo results. [2]
The basement membrane, also known as base membrane, is a thin, pliable sheet-like type of extracellular matrix that provides cell and tissue support and acts as a platform for complex signalling. [1] [2] The basement membrane sits between epithelial tissues including mesothelium and endothelium, and the underlying connective tissue. [3] [4]
Magnetic 3D bioprinting is an alternative to other 3D printing methods such as extrusion, photolithography, and stereolithography.Benefits of the technique include its rapid process (15 minutes – 1 hour), compared to the often days-long processes of others, [4] [5] the capacity for endogenous synthesis of extracellular matrix (ECM) without the need for an artificial protein substrate and ...
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
[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.
