2. Materials and methods

2.4. Total RNA isolation and microarray analysis

Differences in gene expression in subject groups of rBM-MSCs or microglia were analysed using the Illumina system (Illumina, USA) in conjunction with Sentrix Rat-Ref-12-v1 Expression Bead Chips including gene-specific oligonucleotides (~22,000 genes, Illumina, USA). Briefly, Total RNA was isolated with TRIzol reagent (Invitrogen, Carlsbad, CA, USA) according to standard procedures. And the RNA quality and integrity were checked using Agilent Bioanalyzer Nano chip. c RNA amplification and labeling with biotin were performed using Illumina total prep RNA amplification kit (ambion, Inc., austin, TX) with 250 ng of total RNA as input material. cRNA yields were quantified with Agilent Bioanalyzer and 1.5 μg of cRNA was hybridized to Expression Bead Chip. cRNA was hybridized to arrays for 16 h at 58°C, washed and stained with streptavidin-Cy3 according to the manufacturer's protocol. Then the bead chips were centrifuged to dry and scanned on the Illumina

Bead Array Reader confocal scanner. Differences in data distribution were analysed using Bead Studio software (Illumina, USA). Probe signals were quantile normalised, and those with a p-value of less than 0.05 were selected for further analysis.

2.5. Transcriptomic analysis using Ingenuity Pathway Analysis

Gene ontology and biological pathways and functions were determined using the web-based bioinformatics software Ingenuity Pathway Analysis (IPA; Ingenuity Systems, USA). A ±1.2 fold-change in expression levels was used as a cut-off to produce data sets of genes with a significantly changed expression. When a stringent

±1.5 cut-off was applied, the groups (experimental and control) cannot be assessed and the biological function of the gene network cannot be predicted. This is mainly because of the low abundance of changed genes (Figure 3,4, and 5). Genes related to same molecular functions were grouped and depicted as a network with indicate direct and indirect relationships as previous reported (31, 32).

2.6. Quantitative real-time PCR (qPCR)

The expression levels of genes were quantified with qPCR using SsoAdvanced Universal SYBR Green Supermix real-time PCR kit (Bio-Rad, USA) and cDNA and gene-specific primer pairs (Tables 1 and 2) on a Rotor-Gene Q system (Qiagen, USA). Reaction conditions were as follows: 95°C for 5 min, followed by 50 cycles of 95°C for 5 s and 60°C for 30 s. The threshold/quantification cycle (Ct/Cq) value was determined as the point where the detected fluorescence was statistically higher than the background levels. PCR products were analysed using melting curves constructed with Rotor-Gene 1.7 software (Qiagen, USA). PCR reactions were prepared independently in triplicates. Relative quantification of target gene expression was calculated using the 2−ΔΔCt method.

2.7. Migration assay

Migratory activity of rBM-MSCs was determined using an 8 μm pore-size transwell system (Corning, USA). The upper side of the insert was coated with Matrigel (1: 10 dilution in 0.01M Tris (pH 8.0), 0.7% NaCl, Corning, USA) for 2 h at 37°C. The bottom chambers contained one of five different conditions for comparison: MEM with 10% FBS as positive control, MEM without FBS as negative control, MEM with 100 ng/mL LPS, 5 × 104 microglia with MEM, and LPS-stimulated 5 × 104 microglia with MEM. Inserts containing 2.5 × 104 rBM-MSCs were overlaid onto each conditioned well and incubated for 12 h. The inserts were gently washed with cold phosphate-buffered saline (PBS), and non-migrating cells remaining in the upper side of the inserts were removed with a cotton swab. The insert was fixed in Cytofix buffer (BD, San Jose, CA, USA) at 4°C for 30 min and stained with 10 μg/mL Hoechst 33342 at RT for 10 min. After washing twice with PBS, images were acquired using an Axiovert 200M fluorescence microscope (Zeiss, Jena, Germany). The excitation wavelength for Hoechst 33342 was 405 nm.

Migrating cells were counted in ten random 378.27 mm2 (710.52 μm× 532.38 μm) microscopic fields using ImageJ software.

2.8. Statistical analysis

Results were analysed using one-way analysis of variance (ANOVA) with Bonferroni’s multiple comparison test as a post hoc test and IBM-SPSS software (IBM, USA). I performed more than three independent experiments and carried out statistical analysis. Differences were considered significant for p values < 0 05.

3. Results

3.1. Cellular movement-related transcriptomic changes in rat bone marrow- derived mesenchymal stem cells (rBM-MSCs) cocultured with LPS-stimulated microglia

To evalutate the effect of LPS-stimulated microglia on rBM-MSCs, an in vitro coculture method was used (Figure 6(a)). For this study, rBM-MSCs were isolated from 8–12-week-old SD rats and primary microglia from the midbrain of 1-day-old rat pups. Groups of rBM-MSCs were seeded onto the bottom chamber and subjected to 4 different conditions (groups 1–4). Group 1 was the rBM-MSC-only control, group 2 was the coculture with microglia, group 3 was the LPS-treated rBM-MSCs, and group 4 was the coculture with LPS-stimulated microglia. There were no significant changes in cell density of rBM-MSCs (data not shown). In a microarray distribution analysis, gene expression was altered in groups 2, 3, and 4 compared to that of the control (Figure 7). Additionally, the most pronounced variation in the gene expression pattern was observed in group 4. Gene ontology analysis of the transcriptome from group 4 revealed that genes from several canonical pathways such as interferon signalling, death receptor signalling, hepatic fibrosis, and neuroinflammation showed variation in expression levels (Table 3). Expression of genes related to cellular functions, including death, survival, cell cycle, and cellular movement, was also highly altered in group 4 (Figure 8). I focused on the role of cell movement, because the homing of MSCs to the injury site is important for exerting anti-inflammatory effects (33). For detailed transcriptomic analysis of cellular movement, Genes related to cellular movement with altered expression were selected by IPA (Figure 6(b)). Heat map analysis showed clear differences in the gene expression pattern in group 4 compared to the control (Figure 6(c)).

3.2. Functional prediction of transcriptomic networks in rBM-MSCs cocultured with LPS-stimulated microglia

To acquire detailed information of the genes showing variation in expression, Cell movement-related gene expression networks of groups 2, 3, and 4 compared to the network of group 1 were generated using IPA (Figure 9). The most pronounced alternation in the gene expression networks were also observed in group 4, and the related genes were linked with direct relationships. Based on up- or downregulation and stream relationships, prediction analysis of the networks showed that cell migration is predicted to be activated in group 4 (Figure 10(a) and Table 4). Four genes with altered expression levels were identified as being highly related to the migratory activity of cells, which was confirmed using quantitative qPCR (Figure 10(b)). The expression levels of matrix metallopeptidases 3 and 9 (Mmp3 and Mmp9, resp.), vascular cell adhesion protein 1 (Vcam1), and intercellular adhesion molecule 1 (Icam1) were significantly higher in group 4 than in group 2.

3.3. Increased migratory activity in rBM-MSCs cocultured with LPS-stimulated microglia

Based on the transcriptomic analysis and prediction, there were changes in migratory activity of rBM-MSC influenced by LPS-stimulated microglia. To test the prediction, FBS-containing media condition was used as positive control, and the number of migrating cells was significantly increased in rBM-MSCs when cocultured with LPS-stimulated microglia (Figures 11(a) and 11(b)).

3.4. Transcriptomic analysis in LPS-stimulated microglia cocultured with rBM-MSCs

The effects of rBM-MSCs on LPS-stimulated microglia were also determined via reversed conditions of the aforementioned coculture system in vitro. To that end, microglia were seeded on the bottom chamber as subject groups and subjected to 3 different conditions: control, LPS stimulation, and LPS stimulation with rBM-MSC coculture (Figure 12(a)). There were no significant changes in cell density of microglia (data not shown). The transcriptome of subject groups was analysed using microarrays and IPA. Comparison between LPS stimulation and LPS stimulation with rBM-MSC coculture showed changes in expression levels of genes related to cancer, organismal injury and abnormalities, and cell death (Figure 13). Gene ontology analysis of the transcriptome revealed altered expression levels of genes related to inflammatory response related canonical pathways such as triggering receptor expressed on myeloid cell 1 (TREM1) signalling, neuroinflammation, and rheumatoid arthritis (Table 4 and Figure 12(b)). Expression of genes related to TREM1 signalling and neuroinflammation was especially suppressed, as predicted (negative z-score). Focused gene expression analysis of the inflammatory response showed significantly altered levels in 64 genes between groups (Figure 12(c)).

Although the differences were more pronounced after LPS stimulation, remarkable changes were also observed between the presence and absence of rBM-MSCs.

3.5. Functional prediction of transcriptomic networks and reduced inflammatory response in LPS-stimulated microglia cocultured with rBM-MSCs

To examine differences in transcriptomes between LPS-stimulated microglia with and without rBM-MSCs, gene expression networks related to inflammatory were generated using IPA in the corresponding groups (Figure 14 and Table 5). A total of 65 genes highly related to the inflammatory response were identified, and the genes were directly linked. Based on the differential expression (upregulation or downregulation), prediction analysis of networks showed that the inflammatory response is predicted to be inhibited by rBM-MSCs (Figure 15(a) and Table 6). Three genes with altered expression levels were highly related to inflammation, which was confirmed using qPCR (Figure 15(b)). LPS-induced upregulated levels of tumor necrosis factor (Tnf), C-C motif chemokine ligand 2 (Ccl2), and toll-like receptor 2 (Tlr2) genes were significantly decreased after coculture with rBM-MSCs. These predicted functional results were confirmed in experiments using cell cultures, where the number of activated cells induced by LPS stimulation showing swelled and round morphology was significantly decreased by rBM-MSCs (Figure 15(c)). Moreover, the levels of protein markers for microglial activation, CD40 and CD74, were also lower in the presence of rBM-MSC than after LPS stimulation without rBM-MSC, indicating that direct phenotypical activation of microglia was reduced by rBM-MSCs (Figure 16).
