Figure 4.
LtfiCre/+ shows limited recombination of loxP sites in other tissues. Conditional gene recombination induced by Ltf-iCre was visualized by lacZ staining. All samples are from 60-day-old females. Images in the left panels represent lower magnification, and those in the right panels are of higher magnification. Arrows indicate lacZ-positive staining.
