FIG. 5. The PR-B isoform mediates tissue-selective mammary gland tertiary ductal side branching and alveologenesis. (A) Thoracic mammary gland whole mounts of untreated (control) or E + P (EP) treated WT, PRAKO-/-, and PRKO mice. Scale bar = 500 µm. (B) Terminal ductal and alveolar structures visualized in the WT and PRAKO-/- mice using cytokeratin-14 immunofluorescence that specifically labels myepithelial cells. Scale bar = 20 µm.
