Bottom Line: Lead nitrate caused degeneration, necrosis, interstitial edema, and reduction in spermatogenic activity in some seminiferous tubules.It was concluded that lead is a gonadotoxic with a tendency of suppressing semen characteristics and testosterone levels of animals, the presence of MSCs was found to alleviate the toxic effects of lead.We conclude that MSCs derived from the bone marrow of rats can be an effective therapy of LN induced gonado toxicity, thus can contribute to the treatment of infertility.

ABSTRACT

Introduction: The present study aimed to elucidate the therapeutic effects of mesenchymal stem cells (MSCs) derived from the bone marrow of rats (BM) against toxic effects of lead (Pb) on the male gonads of experimental rats.

Methods: The experimental animals were exposed to lead in the form of lead nitrate (LN) one quarter of the LD50. The efficacy of MSCs to reduce gonado-totoxicity induced by lead nitrate at 21, 30 and 60 days, was evaluated experimentally in male rats.

Results: The results showed that testosterone levels and semen quality ameliorated following treatment with MSCs. Also, superoxide dismutase, glutathione peroxidase and catalase levels were increased 21, 30 and 60 days post treatment of MSCs. Moreover, a decrease in genomic DNA alteration and percentage of fragmented DNA was recorded after MSCs treatment. Lead nitrate caused degeneration, necrosis, interstitial edema, and reduction in spermatogenic activity in some seminiferous tubules. The LN-induced changes in histopathologic findings of testis were partially reversed by treatment with MSCs. Histological examination of testis showed deformities in morphology of testis in test animals with gross damage within the seminiferous tubules in Lead nitrate group. The LN-induced changes in histopathologic findings of testis were partially reversed by treatment of MSCs.

Conclusions: It was concluded that lead is a gonadotoxic with a tendency of suppressing semen characteristics and testosterone levels of animals, the presence of MSCs was found to alleviate the toxic effects of lead. We conclude that MSCs derived from the bone marrow of rats can be an effective therapy of LN induced gonado toxicity, thus can contribute to the treatment of infertility.

Fig4: Effect of treatments on serum testosterone and total protein levels after 21, 30 and 60 days of exposure.

Mentions: As shown in Figure 4, LN caused a significant decline (P < 0.05) in testosterone level (0.22 ± 0.05, 0.095 ± 0.007 and 0.17 ± 0.004) at 21, 30 and 60 days, respectively, after treatment as compared to control rats (0.43 ± 0.02). The data revealed that MSCs modulated this decline of serum testosterone level post 21, 30 and 60 days and approached control values, especially after 60 days (0.388 ± 0.06). LN exposure significantly decreased (P<0.05) total protein level at 21, 30 and 60 days. Meanwhile, after 30 and 60 days of MSCs treatment the level of total protein was increased significantly as compared to the untreated rats (Figure 3).Figure 4
