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

Figure 6

Isolated cells are suspended in fibrin gel solution. The cell suspension is added into cross-linking agent solution dropwise to form microbeads (a). The microbeads are mixed into injectable scaffold solution and injected into a mold (b). The microbeads degrade gradually and leave micropores in the three-dimensional scaffold for the migration and proliferation of released cells (c).
