To evaluate the efficacy of adipose-tissue-derived mesenchymal stem cells in regenerating spermatogenesis and restoring fertility in a busulfan-induced rat model of azoospermia.
Induced azoospermia via busulfan administration in male rats (N=20) and transplanted GFP-labeled adipose-derived mesenchymal stem cells into the rete testes.
Evaluated testicular dimensions, histology, and stem cell transdifferentiation using immunohistochemical staining for VASA and SCP1 at 12 weeks post-transplantation.
Conducted natural mating trials with treated rats to assess functional fertility restoration and transmission of the GFP marker to offspring.
Mesenchymal stem cell-treated testes exhibited normal morphology with active spermatogenesis in select tubules, whereas untreated control testes remained atrophic with empty seminiferous tubules.
Immunohistochemical detection of GFP(+)/VASA(+) and GFP(+)/SCP1(+) cells confirmed the transdifferentiation of adipose-derived stem cells into functional spermatogenetic lineages.
Treated rats achieved full fertility recovery through successful mating, yielding continuous generations of offspring that expressed the GFP marker in sperm.
