Figure 6

Three-dimensional image of the EGFP-positive conceptus in the uterus of wild-type mice. The EGFP-positive conceptus in the EGFP-negative uterus of wild-type mice was created by mating CAG-EGFP male mice with wild-type ICR female mice. Pregnant mice were transcardially perfused with 4% PFA and PI solution at E10.5. After the isolated reproductive organs were subjected to CUBIC, 3D and cross-sectional images of the EGFP-positive conceptus in the EGFP-negative uterus of wild-type mice were taken using a light-sheet microscope. A whole 3D image (a) and a sectional image within a blue square of the left panel (b) are shown. Note that fluorescence was clearly visible in the EGFP-positive conceptus, including the placenta and embryo. Scale bars, 1 mm.
