Expression analysis of conserved microRNAs in all six libraries.

<p><b>(A).</b> Real time PCR studies: the relative abundance/expression of seven conserved microRNAs (3D view). <b>(B).</b> Heat maps of microRNAs expression profiles. Fold change of seven microRNAs that were conserved among the libraries based on deep sequencing data. Box represents the color coding of the heat map with the numbers indicating relative signal intensity.
