Abstract
The aims of this study were to examine the effects of CdCl2 on the viability, migration and cytoskeleton of cultured mouse TM4 Sertoli cells. Time- and concentration-dependent changes were exhibited by the cells but 1μM CdCl2 was sub-cytotoxic at all time-points. Exposure to 1 and 12μM CdCl2 for 4h resulted in disruption of the leading edge, as determined by chemical staining. Cell migration was inhibited by both 1 and 12μM CdCl2 in a scratch assay monitored by live cell imaging, although exposure to the higher concentration was associated with cell death. Western blotting and immunofluorescence staining indicated that CdCl2 caused a concentration dependent reduction in actin and tubulin levels. Exposure to Cd2+ also resulted in significant changes in the levels and/or phosphorylation status of the microtubule and microfilament destabilising proteins cofilin and stathmin, suggesting disruption of cytoskeletal dynamics. Given that 1–12μM Cd2+ is attainable in vivo, our findings are consistent with the possibility that Cd2+ induced impairment of testicular development and reproductive health may involve a combination of reduced Sertoli cell migration and impaired Sertoli cell viability depending on the timing, level and duration of exposure.
