MSC morphology on AM. BM-dMSC were cultured at 30,000 cells/cm2 (A) or 180,000 cells/cm2 (B and C) and ASC were cultured at 30,000 cells/cm2 (D) or 180,000 cells/cm2 (E and F) on the stromal side of AM in duplicate. MSC morphology was observed at 48 h of culture by scanning electron microscopy. The stromal side of AM without MSC is presented on (G). Scale bars: (A–F) 200 μm; (G) 2 μm.
