Project description:In regenerative medicine, histocompatibility of pluripotent stem cells is required to solve the problem of immunorejection after therapeutic transplantation. In this study, we show that autologous germline stem cells (GSCs), often called spermatogonial stem cells, could be derived by testis biopsy from individual mice and that GSCs subsequently could be dedifferentiated into autologous germline-derived pluripotent stem (gPS) cells. The establishment of GSCs by testicular biopsy in the mouse model can prove the principle of human clinical application to derive autologous GSCs to generate patient-specific pluripotent cells for regenerative medicine.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.

For transcriptome profiling, 400 ng of total DNA-free RNA was used as input for labelled cRNA synthesis (Illumina TotalPrep RNA Amplification Kit - Ambion) following the manufacturer's instructions (IVT: 12h). Quality-checked cRNA samples were hybridized as biological or technical duplicates for 18 h onto mouse-8 v2 expression BeadChips (Illumina), washed, stained, and scanned following guidelines and using materials / instrumentation supplied / suggested by the manufacturer 13 samples were analyzed, GSC1: Mouse Germ Stem Cells OG2, line 1 (1 replicate); GSC2: Mouse Germ Stem Cells OG2, line 2 (1 replicate); GSC3: Mouse Germ Stem Cells OG2, line 3 (1 replicate); GSCr1: Mouse Germ Stem Cells OG2-ROSA, line 1 (1 replicate); GSCr2: Mouse Germ Stem Cells OG2-ROSA, line 2 (2 replicate); GSCr3: Mouse Germ Stem Cells OG2-ROSA, line 3 (1 replicate); ESC: Mouse Embryonic Stem Cells (duplicate) gPS1: Mouse clonal germ Pluripotent Stem cells from OG2, line 1, (1 replicate); gPS2: Mouse clonal germ Pluripotent Stem cells from OG2, line 2, (1 replicate); gPS3: Mouse clonal germ Pluripotent Stem cells from OG2, line 3, (1 replicate); gPSr1: Mouse clonal germ Pluripotent Stem cells from OG2-ROSA, line 1, (1 replicate); gPSr2: Mouse clonal germ Pluripotent Stem cells from OG2-ROSA, line 2, (1 replicate); gPSr3: Mouse clonal germ Pluripotent Stem cells from OG2-ROSA, line 3, (1 replicate).
Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 5,264 nuclei in mouse adult testis. This dataset includes two samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.
