In our study, we aimed for an efficient hepatic differentiation protocol that is applicable for both maGSCs and embryonic stem cells (ESCs). We attempted to accomplish this goal by using a new established co-culture system with OP9 stroma cells for direct differentiation of maGSCs and ESCs into hepatic cells. We found that the hepatic differentiation of maGSCs was induced by the OP9 co-culture system in comparison to the gelatin culture. Furthermore, we showed that the combination of OP9 co-culture with activin A resulted in the increased expression of endodermal and early hepatic markers Gata4, Sox17, Foxa2, Hnf4, Afp, and Ttr compared to differentiated cells on gelatin or on OP9 alone. Moreover, the hepatic progenitors were capable of differentiating further into mature hepatic cells, demonstrated by the expression of liver-specific markers Aat, Alb, Tdo2, Krt18, Krt8, Krt19, Cps1, Sek, Cyp7a1, Otc, and Pah. A high percentage of maGSC-derived hepatic progenitors (51% AFP- and 61% DLK1-positive) and mature hepatic-like cells (26% ALB-positive) were achieved using this OP9 co-culture system. These generated hepatic cells successfully demonstrated in vitro functions associated with mature hepatocytes, including albumin and urea secretion, glycogen storage, and uptake of low-density lipoprotein. The established co-culture system for maGSCs into functional hepatic cells might serve as a suitable model to delineate the differentiation process for the generation of high numbers of mature hepatocytes in humans without genetic manipulations and make germ line–derived stem cells a potential autologous and alternative cell source for hepatic transplants in metabolic liver disorders."],["dc.identifier.doi","10.1089/cell.2013.0057"],["dc.identifier.gro","3144969"],["dc.identifier.pmid","24380658"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/2652"],["dc.language.iso","en"],["dc.notes.intern","Crossref Import"],["dc.notes.status","final"],["dc.relation.issn","2152-4971"],["dc.title","Efficient Generation of Hepatic Cells from Multipotent Adult Mouse Germ-Line Stem Cells Using an OP9 Co-Culture System"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

To study how mitochondrial function is impaired in BTHS patients, we generated induced pluripotent stem cells (iPSCs) to develop a novel and relevant human model system for BTHS. BTHS-iPSCs generated from dermal fibroblasts of three patients with different mutations in TAZ1 expressed pluripotency markers, and were able to differentiate into cells derived from all three germ layers both in vitro and in vivo. We used these cells to study the impact of tafazzin deficiency on mitochondria( oxidative phosphorylation. We found an impaired remodeling of cardiolipin, a dramatic decrease in basal oxygen consumption rate and in the maximal respiratory capacity in BTHS-iPSCs. Simultaneous measurement of extra-cellular acidification rate allowed us a thorough assessment of the metabolic deficiency in BTHS patients. Blue native gel analyses revealed that decreased respiration coincided with dramatic structural changes in respiratory chain supercomplexes leading to a massive increase in generation of reactive oxygen species. Our data demonstrate that BTHS-iPSCs are capable of modeling BTHS by recapitulating the disease phenotype and thus are important tools for studying the disease mechanism. (C) 2013 The Authors.

We previously described multipotent adult germline stem cells (maGSCs) from mouse testis with differentiation potential similar to embryonic stem cells. The aim of this work was to differentiate maGSCs into functional endothelial cells and to study their potential for vasculogenesis. MaGSCs were cocultivated with OP9 stromal cells to induce differentiation into cardiovascular progenitors, i.e. fetal liver kinase 1-positive (Flk-1(+)) cells. Five days later, Flk-1(+) cells were separated using fluorescence-activated cell sorting, followed by cultivation on collagen type IV under endothelial differentiation conditions. At different time points, maGSC-derived endothelial-like cells were characterized using RT-PCR, flow cytometry, immunofluorescence and functional assays. Cultivation of Flk-1(+) cells resulted in the progressive upregulation of endothelial cell markers, including VE-cadherin, von Willebrand factor and endothelial nitric oxide synthase. Moreover, Flk-1(+) maGSC-derived endothelial-like cells were able to branch and form networks in vitro and promoted functional blood vessel formation in vivo. Importantly, Flk-1(+) cells retained their potential to proliferate and could be continuously expanded, while the ability of contact inhibition was preserved. Thus, maGSCs may provide a useful source of endothelial-like cells to study the basic mechanisms of vasculogenesis or endothelial differentiation. Copyright 2012S.
