Fig. 3. Morphology of female virgin glands shows that
N89ß-catenin induces precocious development in the
presence and absence of PR. Carmine-stained wholemounts of inguinal
mammary glands from 12-week-old (A-D) and 26-week-old (E-H)
virgin mice. Precocious development is not observed in
PR+/- (A,E) or PR-/- (C,G) glands but
is seen in PR+/-;
N89ß-catenin (B,F) and
PR-/-;
N89ß-catenin (D,H) glands, respectively.
LN, lymph node. Brackets (F,H) indicate the regions that are magnified in
