Abstract:
Objective To establish the model of serum-caused damage to pulmonary microvascular endothelial cells (PMVECs) of mice with renal ischemia-reperfusion (I/R) injury.Methods Mice PMVECs were cultured to measure the standard trans-endothelial electrical resistance (TER) in the monolayer of PMVECs.When PMVECs were cultured and arranged in compact monolayer and TER was achieved,they were divided into 4 groups (n =3 each) using a random number table:serum of normal mice group (NS group) and different concentrations (5%,10% and 20%) of serum of mice with renal I/R injury groups (IRS5 group,IRS10group and IRS20 group).The PMVECs were cultured for 1 h in the serum-free endothelial culture medium.The 0.8 and 0.2 ml culture medium containing 20% serum of normal mice were then added to the upper and lower chambers,respectively,in group NS.The 0.8 and 0.2 ml culture medium containing 5%,10% and 20% serum of mice with renal I/R injury were then added to the upper and lower chambers in IRS5,IRS10 and IRS20 groups,respectively.100 μg/ml FITC-BSA 100 μl was added to the upper chamber in the four groups.At 3,6,9,12,15,18,21 and 24 h of incubation,the PMVEC monolayer permeability (apparent permeability coefficient,Pa) was detected.Results Compared with NS group,the Pa was significantly increased at 12 and 15 h of incubation in IRS5 group,and the Pa was increased at 6-24 h of incubation in IRS10 and IRS20 groups.Compared with IRS5 group,the Pa at 21 and 24 h in IRS10 group and at 9-24 h in IRS20 group were significantly increased.Conclusion Both 10% and 20% serum of mice with renal I/R injury can successfully establish the model of damage to PMVECs,and 20% serum causes a more severe damage.
