Description:
Somatic cell nuclear transfer and transcription-factor-based reprogramming revert adult cells to an embryonic state, and yield pluripotent stem cells that can generate all tissues. Through different mechanisms and kinetics, these two reprogramming methods reset genomic methylation, an epigenetic modification of DNA that influences gene expression, leading us to hypothesize that the resulting pluripotent stem cells might have different properties. Here we observe that low-passage induced pluripotent stem cells (iPSCs) derived by factor-based reprogramming of adult murine tissues harbour residual DNA methylation signatures characteristic of their somatic tissue of origin, which favours their differentiation along lineages related to the donor cell, while restricting alternative cell fates. Such an 'epigenetic memory' of the donor tissue could be reset by differentiation and serial reprogramming, or by treatment of iPSCs with chromatin-modifying drugs. In contrast, the differentiation and methylation of nuclear-transfer-derived pluripotent stem cells were more similar to classical embryonic stem cells than were iPSCs. Our data indicate that nuclear transfer is more effective at establishing the ground state of pluripotency than factor-based reprogramming, which can leave an epigenetic memory of the tissue of origin that may influence efforts at directed differentiation for applications in disease modelling or treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150836/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150836/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, K -- Doi, A -- Wen, B -- Ng, K -- Zhao, R -- Cahan, P -- Kim, J -- Aryee, M J -- Ji, H -- Ehrlich, L I R -- Yabuuchi, A -- Takeuchi, A -- Cunniff, K C -- Hongguang, H -- McKinney-Freeman, S -- Naveiras, O -- Yoon, T J -- Irizarry, R A -- Jung, N -- Seita, J -- Hanna, J -- Murakami, P -- Jaenisch, R -- Weissleder, R -- Orkin, S H -- Weissman, I L -- Feinberg, A P -- Daley, G Q -- CA86065/CA/NCI NIH HHS/ -- DP1 OD000256/OD/NIH HHS/ -- DP1 OD000256-01/OD/NIH HHS/ -- HL099999/HL/NHLBI NIH HHS/ -- K99 HL093212/HL/NHLBI NIH HHS/ -- K99 HL093212-01/HL/NHLBI NIH HHS/ -- K99 HL093212-02/HL/NHLBI NIH HHS/ -- K99HL093212-01/HL/NHLBI NIH HHS/ -- P50HG003233/HG/NHGRI NIH HHS/ -- R01 CA086065/CA/NCI NIH HHS/ -- R01 DK059279/DK/NIDDK NIH HHS/ -- R01 DK059279-02/DK/NIDDK NIH HHS/ -- R01 DK059279-10/DK/NIDDK NIH HHS/ -- R01 DK070055/DK/NIDDK NIH HHS/ -- R01 DK070055-01/DK/NIDDK NIH HHS/ -- R01 GM083084/GM/NIGMS NIH HHS/ -- R01 GM083084-04/GM/NIGMS NIH HHS/ -- R01-DK59279/DK/NIDDK NIH HHS/ -- R01-DK70055/DK/NIDDK NIH HHS/ -- R01AI047457/AI/NIAID NIH HHS/ -- R01AI047458/AI/NIAID NIH HHS/ -- R37 HD045022/HD/NICHD NIH HHS/ -- R37CA054358/CA/NCI NIH HHS/ -- RC2 HL102815/HL/NHLBI NIH HHS/ -- RC2 HL102815-01/HL/NHLBI NIH HHS/ -- RC2-HL102815/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Sep 16;467(7313):285-90. doi: 10.1038/nature09342.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cell Transplantation Program, Division of Pediatric Hematology/Oncology, Manton Center for Orphan Disease Research, Howard Hughes Medical Institute, Children's Hospital Boston and Dana Farber Cancer Institute, Boston, Massachusetts 02115, USA〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20644535" target="_blank"〉PubMed〈/a〉
