Comet assays and transmission electron microscopy (TEM). A Siberian tiger fibroblast growth curve. B Comet assays show DNA damage in Siberian tiger fibroblasts treated with cadmium (Cd2+) for 24 h. Statistically significant differences compared to the control cells are denoted by a double asterisk (P < 0.01; n = 3). C TEM shows disruption of the subcellular architecture in Siberian tiger fibroblasts treated with Cd2+ for 24 h. a, c, e control cells. b, d, f Cd2+ -treated cells. The scale bars are 5 μm (a), 0.5 μm (b, c, e), and 1 μm (d, f)
