Figure 2. Cellular metabolic activity.

Figure 2

Measured by MTT assay, comparisons made between ES, and non-ES (control) cells. Cells treated with ES for three days (D3) had significantly (p < 0.05) higher metabolic activity at Day 7 and 14 compared to control (C) cells. Cells treated with ES for three (D3) and seven (D7) days had significantly (p < 0.05) higher activity at Day 14 compared to control and D14 cells. Stars on bars indicate significant differences among groups.
