Structural properties of scaffolds: Crucial parameters towards stem cells differentiation

Figure 5 (A) As the rigidity increased, so did cell attachment. Collagen elicited a greater degree of cell attachment, and increased bulk density of the ligand further enhanced this (B) Morphology on functionalized substrates at 8000 cells/cm² for 24 h. ^astatistical difference compared to fibronectin at 10 mg/mL, ^bdifference compared to collagen at 10 mg/mL, ^cdifference compared to preceding substrate compliance.
