hiPSC cultivated on native (A), meso-structured (B), and macro-structured (C) substrates after four days and counterstained by Phaloidin-FITC. It is clear that all substrates allow cell adhesion and growth. The graph (D) shows slightly lower cellularity on the macro-structured substrate four days after seeding. The different superscripts (a/b) express significant differences (p ≤ 0.05).
