MSCs inhibit BV2 microglia proliferation. MSCs and BV2 microglia were cocultured at ratios indicated below the graph, and BV2 proliferation was determined with 3H-TdR incorporation 48 hours after stimulation with 1 μg/ml LPS. Values are expressed as mean ± SD and from a representative of two independent experiments. *P < 0.05; **P < 0.01; ***P < 0.001, compared with respective controls. cpm, counts per minute; 3H-TdR, tritiated thymidine; LPS, lipopolysaccharide; MSCs, mesenchymal stem cells; SD, standard deviation.
