Figure 3. PIM staining for the hypoxic region. Eyes from different genotypes were stained with antibodies against PIM. PIM signal (Green) was strong in Cited2CKO compared to the control. Eyes collected from Cited2fl/fl;HIFfl/fl;Le-Cre+ showed a weaker signal compared to Cited2CKO mice. Saline injection was used as a negative control.
