Abstract

Planarians are an accessible model system to study animal regeneration and stem cells. Over the last two decades, new molecular techniques have provided us with powerful tools to understand whole-body regeneration and pluripotent adult stem cells specifically. We describe a method for performing Chromatin Immunoprecipitation followed by sequencing (ChIP-seq) on planarian cells that relies on FACS to isolate different cell populations followed by immunoprecipitation and library preparation for next-generation sequencing. Whole-genome profiling of histone modifications enables a greater understanding of epigenetic mechanisms in development, pluripotency, and differentiation. This protocol adds to the growing list of functional genomic approaches to study whole-body regeneration in animals.
