Browsing (Epi)genomes: a guide to data resources and epigenome browsers for stem cell researchers.

Over the past years we have witnessed an explosion in the generation of freely available genome-wide data sets, including maps of various histone modifications, transcription factor binding, DNase hypersensitivity, and DNA methylation, which provide valuable resources for data validation, exploration, and hypothesis generation. The goal of this review is to provide the reader with information on where to find many of the data sets and how to utilize the various (epi)genome browsers for display and initial analysis. We provide selected examples to highlight key features and demonstrate the application of these browsers to stem cell biology.
