Combining Self-Assembling Peptide Gels with Three-Dimensional Elastomer Scaffolds.

(a) SEM image of a PEA scaffold with spherical interconnected pores. (b) CryoSEM cross section image of a PEA scaffold loaded with 0.15% (w/v) SAP solution and gelled with PBS. (c) CLSM image of fibroblasts seeded dynamically in PEA scaffolds with the SAP gel in their pores, cultured for 7 days. DAPI stain for nuclei (blue) and phalloidin stain for actin (green). Image corresponds to a 100μm thick internal slice.
