Project description:Comparison of whole genome gene expression profiles of human testis derived ES-like cells with pluripotent stem cells (human embryonic stem cell lines), adult human bone marrow derived mesenchymal stem cells and human dermal fibroblasts. Microarray study with total RNA of three testis derived ES-like cells clusters of one indivual (1) cultured in three different culture conditions A, B,C and embryoid bodies (EB) derived from them at 4, 7, 10, 14 and 18 days of suspension culture. Biological duplicates of human ES cell lines (HUES-1, GFP-hES-3),human bone marrow derived MSC (BMMSC1 and 2) and human dermal fibroblasts (DFB1 and 2) (LONZA CC-2511) at different passages were used as comparison groups.

Project description:Although reported more than once, the generation of pluripotent stem cell populations from human testis remains questionable. We recently showed that the so - called human adult germline stem cells (haGSCs), which were claimed to be pluripotent, showed a gene expression profile comparable to human fibroblasts, suggesting that these cells are originated from a fibroblastic cells. We could derive human testicular fibroblast cells (hTFCs) from several routine testicular biopsies, naming them human testicular fibroblastic cells (hTFCs). The true conversion of unipotent mouse GSCs, also known as spermatogonial stem cells into pluripotent stem cells was recently shown. However, this conversion was not observed for human cells so far. We suggest that hTFCs isolated from routine biopsies can help in the understanding, modeling and also regenerative medicine for various diseases after reprogramming them to human induced pluripotent stem cells (iPS). We successfully reprogrammed hTFCs into human iPS cells by transducing them retrovirally with reprogramming factors as already demonstrated for human dermal fibroblasts. These hTFCs derived iPS cells are comparable with human embryonic stem cells from global gene expression, promoter methylation, and they show pluripotency judged by in vitro and in vivo differentiation. 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 human-8 v3 expression BeadChips (Illumina), washed, stained, and scanned following guidelines and using materials/instrumentation supplied/suggested by the manufacturer. 8 samples were analyzed: NCL: NCL3 hESCs grown on feeders, bulk harvest at semi-sub confluence (1 replicate) HuES6: HuES6 hESCs grown on feeders, bulk harvest at semi-sub confluence (1 replicate) HT3: Human fibroblast-like testis cells, line 3 (1 replicate) HT16: Human fibroblast-like testis cells, line 16 (1 replicate) FS: FS human foreskin fibroblasts (1 replicate) BJ: BJ human fibroblasts (1 replicate) iPS3: hiPSC line 2 derived from HT3 (1 replicate) iPS16: hiPSC line 2 derived from HT16 (1 replicate)

Project description:Classical mouse embryology has established a paradigm of early development drivenby sequential lineage bifurcations. Accordingly, mouse embryonic stem cells derivedfrom early epiblast have lost the potency to produce extraembryonic trophectoderm.We show in contrast that human naive epiblast cells readily make trophectoderm.Inhibition of ERK signalling, instrumental in naive stem cell propagation, unexpectedlypotentiates trophectoderm formation, an effect enhanced by Nodal inhibition.Transcriptome analyses authenticate conversion into trophectoderm with subsequentproduction of syncitiotrophoblast, cytotrophoblast and trophoblast stem cells. Geneticperturbations indicate that NANOG suppresses and TFAP2C enables trophectoderminduction. Consistent with post-implantation progression, trophectoderm potential isextinguished in conventional human pluripotent stem cells, which instead makeamnion. Finally, human embryo epiblasts from late blastocysts efficiently generatetrophectoderm and differentiated trophoblast. Thus, pluripotent cells in the humanembryo retain extraembryonic lineage plasticity and regenerative potential untilimplantation. Harnessing this unanticipated regulative capacity may be beneficial forassisted reproduction technology.

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:Thiele2013 - Testis Leydig cells
The model of testis Leydig cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.
Thiele I, et al
.
Nature Biotechnology
Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:Human primordial germ cells and mouse neonatal and adult germline stem cells are pluripotent and derive embryonic stem cell properties. Here we report the successful establishment of stable pluripotent human adult germline stem cells (haGSCs) derived from spermatogonial cells of adult human testis. Cellular and molecular characterization of haGSCs revealed many similarities to human embryonic stem (hES) cells and haGSCs produced teratomas after subcutaneous transplantation into immunodeficient mice. The haGSCs differentiated into various types of somatic cells of all three germ layers when grown under conditions used to induce the differentiation of hES cells. We conclude that the generation of haGSCs from testicular biopsies may provide simple and non-controversial access to individual cell-based therapy without the ethical and immunological problems associated with hES cells.
