Fig. 4. Statoacoustic ganglia are reduced in size in cdh2 mutants and knockdowns. Statoacoustic ganglia (SAg) were labeled with zn-5 in 36 hpf control (B), glo (C) and cdh2 MO-injected embryos. Circumferences of zn-5 labeled SAgs were measured (A). The average circumference of control SAgs (226.8 µm) was greater than that of cdh2 MO-injected embryos (192.3 µm, P<0.001) and of glo mutant embryos (176.2 µm, P<0.001). Average SAg circumference was smaller in the glo null mutant than in cdh2 MO-injected knockdowns (P<0.05).
