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

Figure 6

Apoptotic cells in the spinal cord of chicken embryos at E10 recognized by the TUNEL method. MeHg-treated and control embryos showed apoptotic cells (arrows) in the mantle and marginal layers. The accompanying graph displays the NA of TUNEL-positive cells in each spinal cord layer. Data are presented as mean ± SEM. . Scale bar: 10 μm.
