Fig 2. Exogenous PTX3 improves the viability of HK-2 cells after ischemic and hypoxic injuries.

Cell viabilities were measured with and without PTX3 at 1, 5, or 10 nm (P1, P5, and P10, respectively) (A) 24 and 48 h after treatment with 0.3 μg/mL A23187 (A0.3) and (B) after exposure to a hypoxic environment (H). We show that PTX3 provides significant cell viability increasing against HK-2 cell injury after 48hr. Values are expressed as means ± s.e.m of at least four independent experiments, *p < 0.05 (n = 4). 'CON' is abbreviated 'control' which is treated nothing.
