Influence of MSC treatment on TNF-α stimulated gene/protein 6 (TSG-6). Western blotting and real-time PCR analysis of TSG-6. Transplantation of MSCs increased the levels of TSG-6 24 and 72 h after ICH compared with the PBS-treated group (A, B). Similar results were observed at the mRNA levels of TSG-6 (C). n = 6 in each time point per group. Data are presented as the mean ± SD. *P < 0.05; **P < 0.01. GAPDH, glyceraldehyde 3-phosphate dehydrogenase; MSCs, mesenchymal stem cells; PBS, phosphate-buffered saline; TSG-6, TNF-α stimulated gene/protein 6.
