miRNA easy kit (Qiagen) was used for RNA isolation, and Qubit and Bioanalyzer for quality control. Following manufacturer's protocol, 10 ng input and SMART-Seq® v4 Ultra® Low Input RNA Kit (Takra Bio) was used for library construction.  Libraries were prepared in 2 batches. Samples were pooled 7-8 per pool, sequenced on Hiseq 2500, paired end sequencing with 125 bp read.
