ABSTRACT
Objective To explore hemodynamic parameter changes in pulmonary arterial hypertension(PAH)treated by transplantation of bone marrow mesenchymal stem cells(MMSCs)in the experimental rats.Methods MMSCs cells were collected from bone marrow of Sprague-Dawleye(SD)rat's femoral and tibial bones,cultured and passaged in vitro,then stained by Hoechst 33342 fluorescence dye stuff.Ninety healthy male SD rats were randomly divided into 3 groups(n=30)normal control group(group N),MMSCs transplanted group(group M),PAH model group(group H).The rats in the two latter groups were given a single subcutaneous crotaline(50 mg/kg)to establish the model of PAH.The rats of group N were injected respectively a single subcutaneous 9 g/L saline water(6 mL/kg).After 21 days,5?109 L-1 MMSCs cultured in 1 mL phosphate-buffered saline were infused into the rats respectively in group M by sublingual vein and 1 mL L-DMEM was given in group H.The indexalso of right ventricle systolic pressure(RVSP),right ventricle hypertrophy index,arterial blood gas analysis and the changes of small pulmonary blood vessel were observed after 28 days.Results The administration of MMSCs 28 days after PAH nearly completely prevented the increase in RVSP with PAH alone [(32.20?2.32)mmHg vs(48.30?1.56)mmHg P
