Small RNAome sequencing delineates the small RNA landscape of pluripotent adult stem cells in the planarian Schmidtea mediterranea.

ABSTRACT: Small noncoding RNAs play a pivotal role in the regulation of gene expression, and are key regulators of animal development. Freshwater planarian exhibits an extraordinary ability to regenerate any missing body parts, representing an emerging model for studying mechanism underlying stem cell regulation and tissue regeneration. Here, we utilized next-generation sequencing (NGS) to identify small RNAs that are expressed in planarian adult stem cells, and are implicated in tissue regeneration. We profiled microRNAs (miRNAs), piwi-interacting RNA (piRNAs), small rDNA-derived RNAs (srRNAs) and endogenous interfering RNAs (endo-siRNAs) population from size 18-30 nt, measured the expression of 244 conserved miRNAs, and identified 41 novel miRNAs and 64 novel endo-siRNAs.
