Figure 3. DPC co-culture protects rat neural cells against OGD.

Figure 3

Co-culture of rat primary neural cells with DPCs afforded neuroprotection against OGD dose-dependently in both Trypan blue and MTT activity assays of cell viability (a–f). The percentages correspond to the ratio of DPCs co-cultured with rat primary neural cells as follows: 1∶1 (100%), 1∶2 (50%), 1∶4 (25%), and 1∶0 (0%). DPCs co-cultured with rat primary neural cells under non-OGD condition did not alter cell viability in both assays (g–l). Asterisk* corresponds to statistically significant difference (p<0.05 vs. 0%). a,g: 0%; b,h: 25%; c,i: 50%; d,j: 100%; e,k: Trypan blue stain quantification; f,l: MTT assay quantification.
