We were the first to derive such mGSCs from SSCs isolated from adult mouse testis and, therefore, called these mGSCs multipotent adult germline stem cells (maGSCs). Here, we comparatively analyzed gene-specific and global DNA methylation profiles as well as the telomerase biology of several maGSC and male ESC lines. We show that undifferentiated maGSCs are very similar to undifferentiated male ESCs with regard to global DNA methylation, methylation of pluripotency marker gene loci, telomerase activity and telomere length. Imprinted gene methylation levels were generally lower in undifferentiated maGSCs than in undifferentiated male ESCs, but, compared with undifferentiated mGSCs derived by other groups, more similar to those of male ESCs. Differentiation of maGSCs increased the methylation of three of the four analyzed imprinted genes to almost somatic methylation patterns, but dramatically decreased global DNA methylation. Our findings further substantiate the pluripotency of maGSCs and their potential for regenerative medicine."],["dc.identifier.doi","10.1093/molehr/gap023"],["dc.identifier.isi","000265952900003"],["dc.identifier.pmid","19297418"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/16675"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","1360-9947"],["dc.title","Comparative methylation profiles and telomerase biology of mouse multipotent adult germline stem cells and embryonic stem cells"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

These results let us to suggest a role for Lrrc34 in the regulation and maintenance of pluripotency. Expression analyses revealed that Lrrc34 is predominantly expressed in pluripotent stem cells and has an impact on the expression of known pluripotency genes, such as Oct4. Methylation studies of the Lrrc34 promoter showed a hypomethylation in undifferentiated stem cells and chromatin immunoprecipitation-quantitative polymerase chain reaction analyses of histone modifications revealed an enrichment of activating histone modifications on the Lrrc34 promoter region. Further, we could verify the nucleolus-the place of ribosome biogenesis-as the major subcellular localization of the LRRC34 protein. We have verified the interaction of LRRC34 with two major nucleolar proteins, Nucleophosmin and Nucleolin, by two independent methods, suggesting a role for Lrrc34 in ribosome biogenesis of pluripotent stem cells. In conclusion, LRRC34 is a novel nucleolar protein that is predominantly expressed in pluripotent stem cells. Its altered expression has an impact on pluripotency-regulating genes and it interacts with proteins known to be involved in ribosome biogenesis.

When injected into an early blastocyst, SSCs contribute to the development of various organs and show germline transmission. Thus, the capacity to form multipotent cells persists in adult mouse testis.

In a differentiation protocol using retinoic acid(RA) and based on a double selection strategy, we have shown that ESCs are able to undergo meiosis and produce haploid male germ cells in vitro. Using this differentiation protocol we have now succeeded to generate haploid male germ cells from maGSCs in vitro. maGSCs derived from a Stra8-EGFP transgenic mouse line were differentiated into stable spermatogonial stages and further cultured.

In the present study, we have identified Zfp819, a KRAB-zinc finger protein, as a novel pluripotency-related factor and characterized its role in pluripotent stem cells. We show that Zfp819 is expressed highly in various types of pluripotent stem cells but not in their differentiated counterparts. We identified the presence of non-canonical nuclear localization signals in particular zinc finger motifs and identified them as responsible for the nuclear localization of Zfp819. Analysis of the Zfp819 promoter region revealed the presence of a transcriptionally active chromatin signature. Moreover, we confirmed the binding of pluripotency-related factors, Oct4, Sox2, and Nanog to the distal promoter region of Zfp819, indicating that the expression of this gene is regulated by a pluripotency transcription factor network. We found that the expression of endogenous retroviral elements (ERVs) such as Intracisternal A Particle (IAP) retrotransposons, Long Interspersed Nuclear Elements (LINE1), and Short Interspersed Nuclear Elements (SINE B1) is significantly upregulated in Zfp819-knockdown (Zfp819_KD) cells. In line with the activation of ERVs, we observed the occurrence of spontaneous DNA damage in Zfp819_KD cells. Furthermore, we tested whether Zfp819 can interact with KAP1, a KRAB-associated protein with a transcriptional repression function, and found the interaction between these two proteins in both in vitro and in vivo experiments. The challenging of Zfp819_KD cells with DNA damaging agent revealed that these cells are inefficient in repairing the damaged DNA, as cells showed presence of gamma H2A.X foci for a prolonged time.

Here, we extended the comparative epigenetic analysis of maGSCs and male ESCs by investigating the second main epigenetic modification in mammals, i.e. global and gene-specific modifications of histones (H3K4 trimethylation, H3K9 acetylation, H3K9 trimethylation and H3K27 trimethylation). Using immunofluorescence staining, flow cytometry and western blot analysis, we show that maGSCs are very similar to male ESCs with regard to global levels and nuclear distribution patterns of these modifications. Chromatin immunoprecipitation real-time PCR analysis of these modifications at the gene-specific level further revealed modification patterns of the pluripotency marker genes Oct4, Sox2 and Nanog in maGSCs that are nearly identical to those of male ESCs. These genes were enriched for activating histone modifications including H3K4me3 and H3K9ac and depleted of repressive histone modifications including H3K27me3 and H3K9me3.

Here, we show that these miRNAs generally characterize pluripotent cells. They are expressed not only in ESCs but also in maGSCs as well as in the F9 embryonic carcinoma cell (ECC) line. In addition, we tested the time-dependent influence of different factors that promote loss of pluripotency on levels of these miRNAs in all three pluripotent cell types. Despite the differences regarding time and extent of differentiation observed between ESCs and maGSCs, expression profiles of both miRNA families showed similarities between these two cell types, suggesting similar underlying mechanisms in maintenance of pluripotency and differentiation. Our results indicate that the 290-miRNA family is connected with Oct-4 and maintenance of the pluripotent state. In contrast, members of the 302-miRNA family are induced during first stages of in vitro differentiation in all cell types tested. Therefore, detection of miRNAs of miR-302 family in pluripotent cells can be attributed to the proportion of spontaneously differentiating cells in cultures of pluripotent cells.

Several lines of evidence have suggested the extensive proliferation activity and pluripotency of prenatal, neonatal and adult germline stem cells. We showed that adult male germline stem cells, spermatogonial stem cells, can be converted into embryonic stem cell-like cells, which can differentiate into the somatic stem cells of three germ layers. Different cell types such as vascular, heart, liver, pancreatic and blood cells could also be obtained from these stem cells. Understanding how spermatogonial stem cells can give rise to pluripotent stem cells and how somatic stem cells differentiate into germ cells could give significant insight into the regulation of developmental totipotency as well as having important implications for male fertility and regenerative medicine."],["dc.identifier.doi","10.1111/j.1469-7580.2008.00930.x"],["dc.identifier.gro","3143270"],["dc.identifier.isi","000257707900003"],["dc.identifier.pmid","18565110"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/765"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Wiley-blackwell"],["dc.publisher.place","Malden"],["dc.relation.conference","International Conference on Advances in Stem Cell Biology"],["dc.relation.eventlocation","Durham Univ, Durham, ENGLAND"],["dc.relation.ispartof","Journal of Anatomy"],["dc.relation.issn","0021-8782"],["dc.title","Potency of germ cells and its relevance for regenerative medicine"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]
