FIG. 2.

Developmental expression of β-galactosidase marker gene integrated into Sox11 gene locus. β-Galactosidase activity was detected colorimetrically with the X-Gal substrate in whole-mount (A to E) and cryotome-sectioned (F to K) heterozygous embryos at 8.5 dpc (A), 9.5 dpc (B), 10.5 dpc (C and D), 12.5 dpc (E to G), and 14.5 dpc (H to K). No X-Gal staining was detected in wild-type littermates under identical conditions. Abbreviations: ba, branchial arches; drg, dorsal root ganglia; ef, earflap; el, eye lid; ge, ganglionic eminence; gt, gut; hb, hindbrain; ht, heart; lb, limb bud; ma, mammary anlage; mz, mantle zone of the spinal cord; ov, otic vesicle; pa, pancreas; sc, spinal cord; so, somite; sp, spleen; st, stomach; sym, sympathetic chain ganglia; vb, vibrissae; vz, ventricular zone of the spinal cord.
