Initial characterization of pgk1- / - mutants and genetic mosaics.

(A–F) Cross sections through the anterior/vestibular region of the otic vesicle (outlined) showing expression of the indicated genes in wild-type embryos and pgk1- / - mutants at the indicated times. (G–J) Lateral views showing isl2b-Gfp expression in live embryos at 30 hpf (G, H) and fgf3 at 24 hpf (I, J). The otic vesicle is outlined. (K–P) Cross sections through the otic vesicle (outlined) showing positions of lineage labeled wild-type cells (red dye) transplanted into a wild-type host (K, M, O) or a pgk1- / - mutant host (L, N, P). Sections are co-stained with DAPI (M, N) and etv5b probe (O, P). Note the absence of etv5bexpression in wild-type cells transplanted into the mutant host (P). (Q) Number of mature Isl1+ SAG neurons at 30 hpf in embryos with the indicated genotypes, except for sagd1 x pgk1 intercross expected to contain roughly 25% each of +/+, sagd1/+, pgk1/+ and sagd1/pgk1 embryos. (R) Percent of wild-type donor cells located in the ventral half of the otic vesicle expressing etv5b in wild-type or pgk1- / - hosts. A total of 151 wild-type donor cells were counted in eight otic vesicles of wild-type host embryos, and 247 wild-type donor cells were counted in eight otic vesicles of pgk1- / - host embryos. (S) Number of Isl1+ SAG neurons (total, anterior and posterior) in wild-type and pgk1- / - mutant embryos at 36 hpf (n = 12), 48 hpf (n = 12) and 120 hpf (n = 4). (T) Number of phalloidin-stained hair cells (anterior/utricular and posterior/saccular) in wild-type and pgk1- / - mutant embryos at 36 hpf (n = 16), 48 hpf (n = 16) and 120 hpf (n = 10). Sample sizes are indicated (S, T).
