Figure 4. Development of non-neural tissues in MeHg treated embryos.

Figure 4

Stage 14 embryos obtained after control (A) or 20μM MeHg (B) exposure during development. Embryos carry a lacZ reporter for the glutathione S-transferase D1 gene (gstD-lacZ), which is expressed in cells of the midgut (mg) and hindgut (hg). Elements of the midgut and hindgut, including the characteristic bend in the hindgut (open arrow, strongly labeled and seen in cross section in this Nomarski image), are properly formed in both control and MeHg treated embryos (anterior is to the left and dorsal is up).
