Definition: How can 3D bioprinting be used to create functional neural tissue?

3D bioprinting is an advanced technology that combines the principles of 3D printing with the field of tissue engineering to create three-dimensional structures of living cells. It involves the precise deposition of bioinks, which are composed of living cells and biomaterials, layer by layer to create complex tissue structures.

Functional neural tissue refers to the specialized cells and structures that make up the nervous system, including neurons, glial cells, and blood vessels. The ability to create functional neural tissue using 3D bioprinting holds great promise for various applications in neuroscience and regenerative medicine.
