3D Bio-Printing arises from the intersection between 3D-printing and cell encapsulation techniques, allowing for the creation of bio-constructs with programmable spatial disposition of cellular and extracellular matrix components (bio-ink) . At the Italian Institute of Technology we are developing a bioprinter based on the microfluidic wet-spinning of cell-laden fibers suitable for many different bio-inks. The use of microfluidic platforms coupled with 3D deposition offers the possibility to define the composition and disposition of different bioinks using a single print-head, allowing for the easy creation of heterogeneous constructs.
The microfluidic platforms can be used to vary on-the-fly the density of cell seeding during the printing process, as well as the composition of the embedding ECM. Furthermore, the manipulation of different bioinks at the microscale permits to produce heterogeneous fibers containing different types of cells, disposed in pre-determined patterns, allowing for the creation of complex and highly reproducible co-culture models.
Immunotherapy on Chip: “Under the Microscope” Drug-induced Modulation of the Immune ResponsePoster
The immune system is a striking example of an integrated information system, engaged in coordinated host-protective activities. Organs-on-chip approach (OOC) models allow the direct simultaneous observation of hundreds of different cells, moving, interacting and responding to signals coming from the microenvironment nearby, that give access to a number of parameters describing the system that must be properly measured and elaborated.READ MORE
