Fig. 1. The expression patterns of ZISH-2 and ZISH-1 mRNA in the spinal cord Lateral views of the spinal cords of embryos hybridized in situ with ZISH-2 and ZISH-1 cRNA in (A) and (B), respectively. [18 hr embryo in (A), 16 hr embryo in (B)] ZISH-2 and ZISH-I mRNA positive cells in the ventral regions of the spinal cord are indicated by arrowheads in (A) and (B), respectively. Somites are denoted by numbers, and the somite borders are indicated by white lines.
