Figure 2.
Mouse prostatic epithelial cells differentiate into luminal and basal cells that make prostate secretory products. Sections were prepared from grafts depicted in Figure 1. Sections were probed with antibodies to lineage-specific markers p63 (A), CK14 (B), CK8/18 (C), and mDLP (D). Arrows point to basally located cells; arrowheads point to luminal cells. Abbreviations: CK, cytokeratin; mDLP, mouse dorsolateral secretory protein; um, micrometer.
