Abstract (original English)
Stem cell transplantation into seminiferous tubules of recipient testis could become a tool for fertility restoration, genetic improvement, or conservation of endangered species. Spermatogonial stem cells (SSCs) are primary candidates for transplantation; however, limited abundance, complexity for isolation and culture, and lack of specific markers have limited their use. Mesenchymal stromal/stem cells (MSCs) are multipotent progenitors that are simple to isolate and culture and possess specific markers for identification, and immune evasive and migratory capacities. The objective of the present study was to evaluate the potential for survival and colonization in seminiferous tubules of two different concentrations of bovine fetal adipose tissue-derived MSCs (AT-MSCs), native of pre-induced, and to compare the fate of bovine adult peripheral blood-derived MSCs (PB-MSCs) and SSCs after allogenic transplantation in testis of recipient bulls. In experiment 1, AT-MSCs at two concentrations (1x10 7 and 2x10 7 ; n = 3) or pre-exposed to 2 μM testosterone and 1 μM retinoic acid (RA) for 14 days (n = 5) were evaluated. In experiment 2, adult PB-MSCs and SSCs (4x10 7 cells each) pre-exposed to Sertoli cell conditioned media (SCs/CM; n = 4) for 14 days were compared. Each cell type was separately labelled with PKH26 and then transplanted into testes of 8-month-old recipient bulls. Four w
