IHC staining of the Lz in placenta. The upper two rows were the expression of Ki67 in the labyrinth, which are 200-fold and 400-fold, respectively. The middle two rows were the expression of ERα in the labyrinth, which are 200-fold and 400-fold, respectively. The bottom two rows were the expression of PR in the labyrinth, which are 200-fold and 400-fold, respectively. The brown colored nuclei indicate the expression of the target protein, and the blue nuclei suggest that the target protein is not expressed.
