FIG. 6.

Proliferating LRSC express total β-catenin and ABC. Representative immunofluorescence images show LRSC at PPD1 colocalizing with (A) β-catenin (yellow arrow) and (B) ABC (yellow arrow). (C) The percentage of LRSC coexpressing β-catenin and ABC in PPD1 and virgin mice. The percentage of LRSC coexpressing β-catenin (D) and ABC (E) at different gestational and postpartum time points. (F) The colocalization of LRSC with both β-catenin/Ki67 and ABC/Ki67 in PPD1 and virgin mice. (G) Representative figures show the triple staining of either (i) BrdU/β-catenin/Ki67 (yellow arrow) or (ii) BrdU/ABC/Ki67 (yellow arrow). Inserts are enlarged figures of LRSC coexpressing two proteins. Data are expressed as mean±SEM, n=3–5 per group. ABC, active β-catenin; Ctrl, virgin mice. *P<0.05, **P<0.01. Scale bar: 20 μm.
