MeHg Developing Exposure Causes DNA Double-Strand Breaks and Elicits Cell Cycle Arrest in Spinal Cord Cells

Figure 2

Thickness of the spinal cord layers in embryos at E10. Observe the evident difference in the size of the spinal cord between the control and MeHg-treated embryos. The graph displays the effect of MeHg treatment on the ependymal, mantle, and marginal layers. Data are expressed as mean ± SEM. and . e: ependymal layer; mg: marginal layer; and mt: mantle layer. Scale bar: 10 μm.
