Cardiac glycoside bufalin fails to kill senescent END-MSCs. a Relative cell viability (%) of control and H2O2-treated senescent END-MSCs in 3 days after treatment with 10–7, 10–6, 10–5 M bufalin. b Relative cell viability (%) of control and etoposide-treated senescent END-MSCs after treatment with 10–6 bufalin. All data correspond to the mean ± SD. Statistical significance was assessed by the Welch’s t test: ns not significant, *p < 0.05
