间充质干细胞临床试验中的问题及其解决策略

人间充质干细胞（mesenchymal s temcells,MSCs）具有多向分化特性、免疫调节作用及体外分离培养扩增操作简便,因此国内外多家单位均开展了MSC临床试验,以预防和治疗异基因骨髓移植后移植物抗宿主病,修复骨和软骨损伤,治疗心肌梗塞和肝脏损伤等多种疾病。然而,越来越多的资料提示,在制订临床应用方案及具体实施过程中,必须考虑到细胞培养用动物血清蛋白的内在化、植入细胞体内存活以及分化专一性等诸多因素。本文综述了临床试验设计中宜注意的问题。

Problematic Issues in Clinical Trials of Mesenchymal Stem Cells and Unraveling Strategies——Review

With the capacities of multiple differentiation, immunoregulatory activities and easy handling for isolation and culture expansion, human bone marrow mesenchymal stem cells (MSCs) have been utilized in clinical trials for the prevention and treatment of graft-versus-host disease in allogeneic bone marrow transplantation, repair of bone and cartilage defects and treatment of cardiac infarction and liver injury. However, increasingly experimental data indicate that a great deal of issues, such as intra-neutralization of calf serum proteins into cultured MSCs, survival of engrafted cells and subsequent cell differentiation tendency, should be in stringent consideration before clinical trials are designed. In this paper, these issues that should be raised and solved in clinical trials with MSCs were reviewed .
