    Beschreibung: Genome sequencing has uncovered a new mutational phenomenon in cancer and congenital disorders called chromothripsis. Chromothripsis is characterized by extensive genomic rearrangements and an oscillating pattern of DNA copy number levels, all curiously restricted to one or a few chromosomes. The mechanism for chromothripsis is unknown, but we previously proposed that it could occur through the physical isolation of chromosomes in aberrant nuclear structures called micronuclei. Here, using a combination of live cell imaging and single-cell genome sequencing, we demonstrate that micronucleus formation can indeed generate a spectrum of genomic rearrangements, some of which recapitulate all known features of chromothripsis. These events are restricted to the mis-segregated chromosome and occur within one cell division. We demonstrate that the mechanism for chromothripsis can involve the fragmentation and subsequent reassembly of a single chromatid from a micronucleus. Collectively, these experiments establish a new mutational process of which chromothripsis is one extreme outcome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4742237/" 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/PMC4742237/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Cheng-Zhong -- Spektor, Alexander -- Cornils, Hauke -- Francis, Joshua M -- Jackson, Emily K -- Liu, Shiwei -- Meyerson, Matthew -- Pellman, David -- GM083299-18/GM/NIGMS NIH HHS/ -- R01 GM061345/GM/NIGMS NIH HHS/ -- R01 GM083299/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jun 11;522(7555):179-84. doi: 10.1038/nature14493.

    Beschreibung: Pluripotency, the ability to generate any cell type of the body, is an evanescent attribute of embryonic cells. Transitory pluripotent cells can be captured at different time points during embryogenesis and maintained as embryonic stem cells or epiblast stem cells in culture. Since ontogenesis is a dynamic process in both space and time, it seems counterintuitive that these two temporal states represent the full spectrum of organismal pluripotency. Here we show that by modulating culture parameters, a stem-cell type with unique spatial characteristics and distinct molecular and functional features, designated as region-selective pluripotent stem cells (rsPSCs), can be efficiently obtained from mouse embryos and primate pluripotent stem cells, including humans. The ease of culturing and editing the genome of human rsPSCs offers advantages for regenerative medicine applications. The unique ability of human rsPSCs to generate post-implantation interspecies chimaeric embryos may facilitate our understanding of early human development and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Jun -- Okamura, Daiji -- Li, Mo -- Suzuki, Keiichiro -- Luo, Chongyuan -- Ma, Li -- He, Yupeng -- Li, Zhongwei -- Benner, Chris -- Tamura, Isao -- Krause, Marie N -- Nery, Joseph R -- Du, Tingting -- Zhang, Zhuzhu -- Hishida, Tomoaki -- Takahashi, Yuta -- Aizawa, Emi -- Kim, Na Young -- Lajara, Jeronimo -- Guillen, Pedro -- Campistol, Josep M -- Esteban, Concepcion Rodriguez -- Ross, Pablo J -- Saghatelian, Alan -- Ren, Bing -- Ecker, Joseph R -- Izpisua Belmonte, Juan Carlos -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 May 21;521(7552):316-21. doi: 10.1038/nature14413.
