Fig. 1From: Intraperitoneally infused human mesenchymal stem cells form aggregates with mouse immune cells and attach to peritoneal organsEffect of mesenchymal stem cells or fibroblast administration on cytokine production in the peritoneum. Mouse IL-10, IL-13, PGE2, IL-4 and IL-12p70 were assayed at 72 h after IP MSC or HBSS (Ctrl) administration into BALB/c mice. a Mouse cytokine production in the peritoneum in response to three donors. b Peritoneal levels of mouse cytokines after administration of various doses of MSC. c Mouse cytokine production in the peritoneum in response to fibroblasts (Fib) compared to HBSS (Ctrl) or mesenchymal stem cell (MSC) administration. *P < 0.05, **P < 0.01, ***P < 0.001, compared to controls.
