Figure 3.

Panels A and B: hASCs (A) and hWJ-MSCs (B) cell counts, expressed as growth rates, calculated as the cell number at each time point divided by the cell number of seeded cells. Data are expressed as mean of growth rates ± SD (n=3, *p<0.05, **p<0.01). Panels C and D: percentage of reduction of Resazurin (as indicator of cell proliferation) after treatment of hASCs (C) and hWJ-MSCs (D) for 2 h with H₂O₂ (50, 100, 150, 200 or 400 μM). Analysis was conducted on a technical quadruplicate at 4, 24, 48, 72 h (C) or at 2, 24, 48, 72 h (D) from the end of the treatment and data are expressed as mean ± SD.
