摘要:
目的 应用超声评价体外不同处理方式兔骨髓间充质干细胞(MSCs)移植于缺血心肌后对心脏功能的影响。方法 采用结扎冠状动脉左前降支的方法建立心肌梗死模型,2周后分别将自体MSCs、经5-aza诱导的MSCs、骨髓单个核细胞(BMMNCs),Dil标记后用微量注射器注射于兔缺血心肌内,并以无血清培养基注射动物为对照组。分别在术前、细胞移植前、细胞移植后2、4周之后行M型超声心动测量:左室收缩末内径(LVESD)、左室舒张末内径(LVEDD),计算左室射血分数(LVEF)、左室短轴缩短率(LVFS)等指标。结果 细胞移植后2、4周,超声心动检查发现MSCs组和5-aza诱导的MSCs 组的兔心功能(LVEF、LVFS值)比对照组显著升高(P<0.05),而BMMNCs组仅在移植后4周明显改善(P<0.05);LVESD、LVEDD细胞移植组与对照组相比无显著差异(P>0.05)。结论 MSCs、经5-aza诱导的MSCs、 BMMNCs均能存活于梗死心肌中,从而改善缺血心肌后左室收缩功能。
Abstract:
Objective To investigate the roles of transplantation of bone marrow-derived mesenchymal stem cells (MSCs) on rabbit post-infarct myocardium and their influences on cardiac function. Methods The myocardial infarction model was made by using coronary artery ligation of the left anterior descending. After 2 weeks, the self pulp MSCs, 5-aza induced MSCs, and bone marrow mononuclear cells (BMMNCs) labeled with Dil were injected into ischemic myocardium of rabbits, and the injection of serum-free media used as the control group. Two-dimensional ultrasound measurements of left ventricular end-systolic diameter (LVESD) , left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) index evaluation cardiac function were carried out before operation, before and after transplantation of 2 weeks and 4 weeks. Results After implantation of 2 and 4 weeks, the myocardial function (LVEF and LVFS value) of rabbits implanted with MSCs, 5-aza induced MSCs was better than control group (P< 0.05). BMMNCs group improved after transplantation of 4 weeks (P < 0.05). No significant difference of LVESD, LVEDD was found between cells transplantation groups and control group (P > 0.05). Conclusion MSCs, 5-aza induced MSCs, BMMNCs were lived in myocardial infarction, and improved left ventricular systolic function after myocardial ischemia.
