Figure 7. Expression of Notch1 in the mouse corneal epithelium after wounding as determined by relative quantitative reverse transcription polymerase chain reaction. The expression levels are presented relative to the baseline unwounded samples. When the rate of proliferation had peaked at 24 h, Notch1 expression was reduced (78%±3%, p<0.001). By 48 h, the expression had recovered and increased beyond the baseline. After six days, Notch1 returned to baseline levels.
