library_construction_protocol: Total RNA was extracted using RNAiso Plus (Takara, Shiga, Japan) and QIAGEN RNeasy® Mini kit (QIAGEN, Hilden, Germany). hMSCs or LPS-treated hMSCs were completely lysed with RNAiso Plus, then 200 μl of chloroform was added, and the tubes inverted for 5 min. The mixture was centrifuged at 12,000 x g for 15 min at 4°C, and the upper phase was placed into a new tube and 600 μl of 70% ethanol was added. The mixture was applied to an RNeasy mini column. The column was washed with wash buffer. To elute, RNase-free water (30 μl) was added directly onto the RNase mini column, followed by centrifugation at 12,000 x g for 3 min at 4°C. For ribosomal RNA (rRNA) depletion in total RNA, the RiboMinus Eukaryote kit (Life Technologies, Carlsbad, CA) was employed according to the manufacturer's instructions. RNA libraries were created using the NEBNext® Ultra™ directional RNA library preparation kit for Illumina® (New England Biolabs, Ipswich, MA). rRNA-depleted total RNA was fragmented into small pieces using divalent cations at elevated temperatures. The first-strand cDNA was synthesized using reverse transcriptase and random primers, and then second-strand cDNA synthesis was performed using DNA polymerase I and RNase H. The cDNA fragments were processed using an end-repair reaction after the addition of a single 'A' base, followed by adapter ligation. These products were purified and amplified through PCR to generate the final cDNA library. RNA libraries were prepared for sequencing using standard Illumina protocols
