Book Description
Nearly all cells of an individual organism contain the same genome. However, each cell type transcribes a different set of genes due to the presence of different sets of cell type-specific transcription factors. Such transcription factors bind to regulatory regions such as promoters and enhancers and regulate their activity in gene transcription. Transcription factors interact with each other and form tissue-specific transcription factor networks. Identification of genome binding and gene regulation by transcription factors will enhance our understanding of how transcription factors specify cell types. Chapter 1 serves as a general introduction into eukaryotic transcription regulation and describes the role of enhancers and transcription factors. Chapters 2 - 4 describe the experimental work of this thesis. Chapter 2 describes Chromatin Immunoprecipitation followed by Mass Spectrometry (ChIP-MS), a technique used to identify transcription factors and other genome binding proteins that bind to promoters, enhancers or heterochromatin. Chapter 2 specifically describes the genome-binding pattern of transcription- and pluripotency factor Dppa2, which we identify by ChIP-MS and ChIP-seq to bind to promoters outside the classical pluripotency network. Chapter 3 describes a transcription factor interaction network of over 200 proteins in neural stem cells, which was assembled by the identification of interaction partners of four mental disorder-associated transcription factors. Chapter 4 describes work on the genome-wide localization of Oct4, Sox2 and Nanog in embryonic stem cells and investigates the genome localization of these transcription factors upon depletion of Oct4 or Sox2 from embryonic stem cells. The last chapter, Chapter 5, summarizes the results from Chapter 2-4 and provides additional discussion to these chapters, concerning its implications and future directions.

Book Description
This volume describes the latest findings on transcriptional and translational regulation of stem cells. Both transcriptional activators and repressors have been shown to be crucial for the maintenance of the stem cell state. A key element of stem cell maintenance is repression of differentiation factors or developmental genes – achieved transcriptionally, epigenetically by the Polycomb complex, and post-transcriptionally by RNA-binding proteins and microRNAs. This volume takes two approaches to this topic – (1) illustrating the general principles outlined above through a series of different stem cell examples – embryonic, iPS and adult stem cells, and (2) describing several molecular families that have been shown to have roles in regulation of multiple stem cell populations.

Book Description
Stem cells have been gaining a lot of attention in recent years. Their unique potential to self-renew and differentiate has turned them into an attractive model for the study of basic biological questions such as cell division, replication, transcription, cell fate decisions, and more. With embryonic stem (ES) cells that can generate each cell type in the mammalian body and adult stem cells that are able to give rise to the cells within a given lineage, basic questions at different developmental stages can be addressed. Importantly, both adult and embryonic stem cells provide an excellent tool for cell therapy, making stem cell research ever more pertinent to regenerative medicine. As the title The Cell Biology of Stem Cells suggests, our book deals with multiple aspects of stem cell biology, ranging from their basic molecular characteristics to the in vivo stem cell trafficking of adult stem cells and the adult stem-cell niche, and ends with a visit to regeneration and cell fate reprogramming. In the first chapter, “Early embryonic cell fate decisions in the mouse”, Amy Ralson and Yojiro Yamanaka describe the mechanisms that support early developmental decisions in the mouse pre-implantation embryo and the current understanding of the source of the most immature stem cell types, which includes ES cells, trophoblast stem (TS) cells and extraembryonic endoderm stem (XEN) cells.

Book Description
Stem Cell Epigenetics, Volume 16, examines how epigenetics are involved in stem cell differentiation, how a stem cell rapidly transitions into a molecularly distinct cell type, and how this process may be reversed or managed via epigenetic reprogramming. Topics discussed include chromatin in pluripotency, epigenetic regulation of reprogramming, stem cells and DNA methylation, histone modifications in stem cells and differentiation, higher-order chromatin conformation in pluripotent cells, epigenetics and disease modeling, organoids from pluripotent cells, transcriptional regulation in stem cells and differentiation, non-coding RNAs in pluripotency and early differentiation, and diseases caused by epigenetic alterations in stem cells. Additionally, the potential implementation of stem cell epigenetics in drug discovery, regenerative medicine, and disease treatment is discussed in detail, helping researchers and physicians bring this exciting and fast evolving field to the clinic. Provides genetic researchers, students and physicians with evidence indicating the epigenetic mechanisms involved in stem cell differentiation Highlights the specific characteristics of the epigenetic modifications and misregulations that may result in disease pathogenesis Examines the potential application of stem cell epigenetics towards developing therapeutic interventions for disease and advancing regenerative medicine Features chapter contributions by leading international experts
