Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0033] The carrier for promoting the self-renewal and proliferation of dairy goat spermatogonial stem cells provided by the present invention uses the Sirt1 gene related to spermatogenesis as the target gene to construct a eukaryotic expression vector, and uses dairy goat spermatogonial stem cells as a host for transduction to promote spermatogenesis. Overexpression or overexpression of the gSirt1 gene in primary stem cells.
[0034] Specifically, the present invention first constructs the eukaryotic expression vector pSirt1-IRES2-AcGFP containing gSirt1 and green fluorescent protein (AcGFP) genes, transfects the vector into male reproductive stem cells of dairy goats, and observes marker gene AcGFP and Sirt1 antibody staining under a fluorescent microscope Its expression was detected, and it...
