Fig. 2From: Limbal niche cells can reduce the angiogenic potential of cultivated oral mucosal epithelial cellsRepresentative images of hematoxylin and eosin staining. Stratified cultivated oral mucosal epithelial cell sheets co-cultured with LNCs (c) and 3 T3 cells (d) had 2–3 layers after airlifting for one week. These cell sheets resembled the normal corneal epithelial cells (b) rather than the native oral mucosal epithelial cells (a). Black arrows indicate the transparent polyethylene terephthalate membrane of culture insert. Scale bars: a: 100 μm, b: 50 μm, c and d: 25 μmBack to article page
