Fig. 2From: Rat limbal niche cells can induce transdifferentiation of oral mucosal epithelial cells into corneal epithelial-like cells in vitroImmunofluorescence of oral mucosa, central cornea, and limbus. Rat oral mucosa, central cornea, and limbus were single-stained for CK3, CK12, Pax6, or ΔNp63α (red fluorescence) or double-stained for ΔNp63α (green fluorescence) and Vim (red fluorescence). Nuclei were stained by DAPI. Scale bar = 100 μmBack to article page
