Fibrin Gel as an Injectable Biodegradable Scaffold and Cell Carrier for Tissue Engineering

Figure 3

Schematic illustration of fabrications of two- and three-dimensional cell culture scaffold. The conventional two-dimensional scaffold is fabricated in advance of cell seeding and the isolated cells are seeded on the surface of scaffold (a). The three-dimensional scaffold cures in the presence of the encapsulated cells. Then, the mixture can be delivered into a mold to gel or directly injected into a defect in the body (b).
