Induction of Pluripotency in Adult Unipotent Germline Stem Cells

ABSTRACT: Mouse and human stem cells with features similar to those of embryonic stem cells have been derived from testicular cells. Although pluripotent stem cells have been obtained from defined germline stem cells (GSCs) of mouse neonatal testis, only multipotent stem cells have been obtained so far from defined cells of mouse adult testis. In this study we describe a robust and reproducible protocol for obtaining germline-derived pluripotent stem (gPS) cells from adult unipotent GSCs. Pluripotency of gPS cells was confirmed by in vitro and in vivo differentiation, including germ cell contribution and transmission. As determined by clonal analyses gPS cells indeed originate from unipotent GSCs. We propose that the conversion process requires a GSC culture microenvironment that depends on the initial number of plated GSCs and the length of culture time. Nine samples were analyzed.

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. 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).
