Effects of HEP induction at the sphere stage on the expression of dorsoventral patterning genes. Embryos from crosses of wild-type and HEP+/- transgenic (Tg) fish were exposed to heat shock at the sphere stage for 1 h, allowed to develop at a lower temperature to 50% epiboly, and then examined for the expression of DV patterning genes (right two columns). Embryos in the third column showed normal patterns (Sibling-HS), whereas those in the rightmost column showed expanded (D, H, L, P) or reduced (T, X) expression (HEP-HS). The numbers of embryos with abnormal expression and total numbers of embryos examined are shown at the bottom of the respective panels in the HEP-HS column. For the control, gene expression was examined in parallel in wild-type embryos that were untreated (left column, Wild) or treated with heat shocks (second column, Wild-HS). Scale bar, 200 μm.
