摘要 目的观察扩张型心肌病(DCM)心肌组织自体骨髓间质干细胞(ABMMSCs)移植,对心脏功能的影响。方法40只日本大耳白兔,随机分成对照组(n=10)与实验组,无菌条件下于髂骨处抽取骨髓6ml,分离ABMMSCs后冻存。实验组动物耳缘静脉注射阿霉素复制DCM模型,8周后再分为移植组(n=15)和非移植组(n=15)。3组动物均做开胸手术,对照组开胸后不做任何处理,移植组左心室前壁注射ABMMSCs,非移植组注射细胞培养液。移植后4周,超声心动及左心导管测定心脏功能,心肌组织HE染色及双重免疫组化分析。结果超声心动显示,细胞移植前,左室射血分数(EF)、左室壁收缩末期厚度(LVWTs)、左室壁舒张末期厚度(LVWTe)、左室收缩末期内径(Ds)、左室舒张末期内径(Dd)、心室率(HR)组间比较,差异有统计学意义(F=5.026、3.879、4.472、3.582、3.952、3.378,P〈0.05);EF、LVWTs、LVWTe,移植组和非移植组与对照组相比,明显减小(P〈0.05),Ds、Dd、HR则明显增加(P〈0.05)。细胞移植后,EF、LVWTs、LVWTe、Ds、Dd、HR组间比较,差异有统计学意义(F=4.487、4.014、4.593、3.425、3.716、3.495,P〈0.05)。EF、LVWTs、LVWTe,移植组较非移植组明显增加(P〈0.05),但仍低于对照组(P〈0.05);而Ds、Dd、HR,移植组虽明显低于非移植组,但仍高于对照组(P〈0.05)。左心导管检查显示,移植后,Ps、Pd、+dp/dt max、HR组间比较,差异有统计学意义(F=4.406、4.918、10.858、3.824,P〈0.05)。两两比较Ps、+dp/dt max,移植组明显高于非移植组(P〈0.05),但低于对照组(P〈0.05);Pd、HR移植组低于非移植组(P〈0.05),但高于对照组(P〈0.05)。移植组的心肌组织内可见抗5-溴脱氧尿苷(BrdU)染色阳性的细胞,这些细胞同时抗肌动蛋� objective To evaluate the effect of autologous bone mesenchymal stem cell (ABMMSCs) transplantation on rabbits with dilated cardiomyopathy(DCM). Methods ABMMSCs were isolated from bone marrow aspirated from adult rabbits and expanded exvivo before DCM was induced. 40 rabbits were divided into 3 groups randomly: transplantation group(n = 15) and non-transplantation group(n = 15) and control group(n = 10). ABMMSCs suspension or culture medium was injected into the myocardium, while the control group(n = 10) underwent thoracotomy solely. For inducing dilated cardiomyopathy, adriamycin was intravenously injected into rabbits for 8 weeks. Before and after transplantation, heart function was evaluated by ultrasonic cardiograph and left heart catheterization. The hearts were harvested and processed for histological and immunohistochemical techniques. Results Before transplantation, ultrasonic cardiography revealed transplantation group and non-transplantation group had lower ejection fraction (EF), decreased end-systolic wall thickness of left ventricular (LVWTs) and end-diastolic wall thickness of left ventricular (LVWTe) (F = 5.026,3.879,4.472,P 〈 0.05 ) ; higher left ventricular end-systolic diameter (Ds), left ventricular end- diastolic diameter(Dd ) and heart rate (HR) (F = 3.582,3.952,3.378, P 〈 0.05 ) versus control group. The transplanted hearts had greater EF, increased LVWTs and LVWTe(P 〈 0.05) ; less Ds, Dd and HR(P 〈 0.05) versus non-transplantation group. Similarly, left heart catheterization showed ABMMSCs transplantation resulted in an increased left ventricular systolic pressure (Ps) along with maximum rate of rise of left ventricular pressure (+ dP/dt max)(P 〈 0.05), and a decreased left ventricular end-diastolic pressure (Pd) and HR compared with those receiving culture medium injection(P 〈 0.05). Some engrafted ABMMSCs in myocardium were positively stained for BrdU and actin, N- cadherin. Conclusions Ad
