Representative images of labeling of inner cell mass and trophectoderm cells.
Blastocysts were harvested at day 7 and subjected to differential immunofluorescence. Blue: Hoescht 33342 staining (all nuclei); green: CDX2+ cells (labeled with mouse anti-CDX2 and FITC-conjugated anti mouse IgG). Trophectoderm cells were labeled with Hoescht and anti CDX2 while inner cell mass cells were labeled with Hoescht only.
