. Anchorage-independent growth of mouse male germline stem cells in vitro. Biol Reprod. 2006;74:522-9 pubmed
..These results indicate that spermatogonial stem cells can undergo anchorage-independent, self-renewal division, and suggest that stem cells have the common property to survive and proliferate in the absence of exogenous substrata. ..

..These results suggest that FBXW7 regulates SSC self-renewal in a negative manner by degradation of MYC. ..
Kanatsu Shinohara M, Naoki H, Shinohara T. Nonrandom Germline Transmission of Mouse Spermatogonial Stem Cells. Dev Cell. 2016;38:248-61 pubmed publisher
..Thus, spermatogenesis is a regulated process whereby specific SSC clones are repeatedly recruited for fertilization with long-term cycles. ..

. Transfer of a Mouse Artificial Chromosome into Spermatogonial Stem Cells Generates Transchromosomic Mice. Stem Cell Reports. 2017;9:1180-1191 pubmed publisher
..Successful transfer of MACs to GSCs overcomes the problems associated with ESC-mediated germline transmission and provides new possibilities in germline modification. ..

. Clonal origin of germ cell colonies after spermatogonial transplantation in mice. Biol Reprod. 2006;75:68-74 pubmed
..These results provide evidence that germ cell colonies develop from single spermatogonial stem cells. ..

. Pluripotency of a single spermatogonial stem cell in mice. Biol Reprod. 2008;78:681-7 pubmed publisher
..Thus, our study provides evidence that a single spermatogonial stem cell can acquire pluripotentiality but that conversion into a pluripotent cell type is accompanied by loss of spermatogenic potential. ..

. Homing of mouse spermatogonial stem cells to germline niche depends on beta1-integrin. Cell Stem Cell. 2008;3:533-42 pubmed publisher
..These results identify beta1-integrin as an essential adhesion receptor for SSC homing and its association with laminin is critical in multiple steps of SSC homing. ..
