To determine whether the Hoechst efflux-dependent side population phenotype identifies and enriches male germline stem cells in adult mouse testes via Bcrp1 transporter activity.
Assayed Hoechst 33342 dye efflux in adult mouse testicular cells in the presence and absence of the specific BCRP1 inhibitor Ko143.
Profiled expression of spermatogonial and germ stem cell markers (Stra8, alpha 6-integrin) in wild-type, W/Wv mutant, and cryptorchid mouse models.
Evaluated the stem cell capacity of sorted testicular side population cells using an in vivo repopulation transplantation assay.
Mouse testicular cells exhibited a distinct side population phenotype driven by Bcrp1 expression and completely blocked by Ko143 inhibition.
The germinal side population expressed key stem and spermatogonial markers, including alpha 6-integrin and Stra8, across normal and impaired spermatogenesis models.
In vivo transplantation confirmed that adult testis side population cells are significantly enriched in functional male germline stem cells capable of repopulating recipient testes.

Implication

Laboratory study demonstrates that Bcrp1-dependent side population sorting enriches functional germ stem cells in adult mice, indicating a reliable marker for isolating male reproductive progenitors.
