FIG. 5.
Tissue-engineered rabbit oral mucosal epithelial cell sheets before and 5 h after transportation. Examination of cell morphology was performed using phase-contrast microscopy: (a) cell sheet before transportation, (b) cell sheet after transportation with KCM, (c) cell sheet after transportation with KCM minus fetal bovine serum and epidermal growth factor, (d) cell sheet after transportation with DMEM/F12, (e) cell sheet after transportation with HBSS. Scale bars: 100 μm. HBSS, Hanks' balanced salt solution; KCM, keratinocyte culture medium.
