Journal ArticleDOI
Epigenetic rejuvenation of mesenchymal stromal cells derived from induced pluripotent stem cells.
Joana Frobel,Hatim Hemeda,Michael Lenz,Giulio Abagnale,Sylvia Joussen,Bernd Denecke,Tomo Saric,Martin Zenke,Wolfgang Wagner +8 more
TL;DR: Overall, iPS-MSCs are similar to MSCs, but they reveal incomplete reacquisition of immunomodulatory function and MSC-specific DNAm patterns—particularly ofDNAm patterns associated with tissue type and aging.
Journal ArticleDOI
Epigenetic Classification of Human Mesenchymal Stromal Cells
Danilo Candido de Almeida,Danilo Candido de Almeida,Marcelo R.P. Ferreira,Marcelo R.P. Ferreira,Julia Franzen,Carola I. Weidner,Joana Frobel,Martin Zenke,Ivan G. Costa,Wolfgang Wagner +9 more
TL;DR: An alternative concept to use DNAm patterns for molecular definition of cell preparations, and the epigenetic scores facilitate robust and cost-effective quality control of MSC cultures are proposed.
Journal ArticleDOI
Leukocyte Counts Based on DNA Methylation at Individual Cytosines.
Joana Frobel,Tanja Božić,Michael Lenz,Michael Lenz,Peter Uciechowski,Yang Han,Reinhild Herwartz,Klaus Strathmann,Susanne Isfort,Jens Panse,André Esser,Carina Birkhofer,Uwe Gerstenmaier,Thomas Kraus,Lothar Rink,Steffen Koschmieder,Wolfgang Wagner +16 more
TL;DR: White blood cell counts can be reliably determined by site-specific DNAm analysis and is applicable to very small blood volumes and frozen samples, and it allows for more standardized and cost-effective analysis in clinical application.
Journal ArticleDOI
DNA-methylation in C1R is a prognostic biomarker for acute myeloid leukemia.
Tanja Božić,Qiong Lin,Joana Frobel,Stefan Wilop,Melanie Hoffmann,Carsten Müller-Tidow,Tim H. Brümmendorf,Edgar Jost,Wolfgang Wagner +8 more
TL;DR: Analysis of DNAm at C1R provides a simple, robust, and cost-effective biomarker to further complement risk assessment in AML, and indicates that DNAm of C1 R is a biomarker reflecting chromatin reorganization rather than being of pathophysiological relevance per se.
Journal ArticleDOI
Epigenetic aging of human hematopoietic cells is not accelerated upon transplantation into mice.
TL;DR: Epigenetic changes of human hematopoietic development are recapitulated in the murine transplantation model, whereas epigenetic aging is not accelerated by the faster aging environment and seems to occur in the cell intrinsically.
