CHBP preconditioning rendered MSCs more resistant to starvation. a MSCs were preconditioned with CHBP at a concentration of 10 nmol/L and then subjected to serum starvation. Apoptosis was detected by Annexin V/PI asaay. b Quantification analysis of flow cytometry results was performed and demonstrated. Experiments were performed in triplicate. Data are expressed as mean ± standard deviation
