Figure 6. Immunofluorescence for Notch1 in the cornea of a wounding mouse model. A: Notch1 expression is noted predominantly in the basal and early suprabasal cells in unwounded mouse corneas. B: Scattered expression of Notch1 is seen in the new epithelium near the leading edge (arrowhead) 24 h after wounding. Nuclei were stained with DAPI in blue. Bar=30 μm.
