About this Research Topic
In recent years, the development of tridimensional (3D) culture systems has attracted the greatest interest to investigate cell biology, as shown by the growing publication rate on this topic. Such 3D systems provide more accurate in vitro models than the traditional 2D systems, not only in terms of cell adhesion, migration, but also in terms of cell response to the microenvironment involving mechanical stimulation, transfer phenomena (oxygen, nutrients), cell-cell contacts, and autocrine/paracrine factors. However, reproducing the native cellular microenvironment during culture, in additional to analyzing its impact, remains challenging since a lot of parameters such as extracellular matrix composition, architecture with specific mechanical properties, medium and growth factors selection, as well as dynamic culture conditions must be addressed to better mimic each targeted tissue.
The development of 3D culture systems is required to investigate biology in tissue environment mimicking physiological process as well as disease progression. The properties of the selected extracellular matrix or biomimetic materials, culture medium composition, the use of bioreactors, and dynamic culture conditions will all have a critical impact on the behaviour of cells, grown alone or in co-cultures (endothelial cells, neurons, multipotent adult mesenchymal stromal cells, pluripotent induced stem cells). The ability to follow the 3D culture systems in real time will also strongly deepen our understanding of the mechanical and biochemical signalling mechanisms governing specific cell behaviour, thus improving tissue engineering strategies. Such 3D culture systems can also play a crucial role in the drug screening and optimization of drug delivery systems.
This Research Topic will therefore show how current cutting-edge advances in engineered extracellular matrix, biomimetic materials, bioprinting strategy, specialized bioreactors, cell co-cultures, should be used to develop the next generation of 3D culture systems and to influence cell fate. In situ monitoring of such systems will help to generate more accurate tissue engineering models for normal or pathological tissues, which will be used in regenerative medicine, but also as efficient drug screening platforms for the development of new therapeutics.
