Figure 6From: Collagen matrices from sponge to nano: new perspectives for tissue engineering of skeletal muscleA: phase contrast microscopy of collagen-I-fibrin gel:24 hours after seeding the cells (arrow-heads) and gel formation, some of the cells are already spread out (arrows), 100× B-C: SEM of the collagen-I fibrin gel after 10 days in culture media, 5000× (B) and 25.000× (C) after fixation for SEM and drying procedure the gel showed micro fibrils forming a sponge-like structure.Back to article page
