Fig. 7. Adrenal chromaffin cell number is reduced in Gata3 mutant
embryos. lacZ expression (A-F) in the adrenal gland of
E13.5 and E15.5 of Gata3z/+ (A,D),
Gata3z/-:TghDBH-G3 (B,E) and
Gata3Z/- (C,F) embryos. (G) Quantification of
ß-gal+ chromaffin cells in embryos of various genotypes. At
least four adrenal glands from two different embryos of each genotype were
analyzed. Data are presented as mean±s.e.m. The statistical
significance of the differences between
Gata3-/-:TghDBH-G3 and Gata3-/- are
indicated by (*P<0.05; Student's t-test).
Scale bars: 100 µm.
