近日,ISCT(国际细胞治疗协会)和 ICCBBA(国际血库自动化通用委员会)在 Elsevier旗下期刊《Cytotherapy》上发布了不同组织来源的间充质干细胞缩写命名的统一标准。
The Cellular Therapy Coding and Labeling Advisory Group of the International Council for Commonality in Blood Banking Automation and the International Society for Cell & Gene Therapy mesenchymal stromal cell (MSC) committee are providing specific recommendations on abbreviating tissue sources of culture-adapted MSCs. These recommendations include using abbreviations d on the ISBT 128 terminology model that specifies standard class names to distinguish cell types and tissue sources for culture-adapted MSCs. Thus, MSCs from bone marrow are MSC(M), MSCs from cord blood are MSC(CB), MSCs from adipose tissue are MSC(AT) and MSCs from Wharton's jelly are MSC(WJ). Additional recommendations include using these abbreviations through the full spectrum of pre-clinical, translational and clinical research for the development of culture-adapted MSC products. This does not apply to basic research focused on investigating the developmental origins, identity or functionalities of endogenous progenitor cells in different tissues. These recommendations will serve to harmonize nomenclature in describing research and development surrounding culture-adapted MSCs, many of which are destined for clinical and/or commercial translation. These recommendations will also serve to align research and development efforts on culture-adapted MSCs with other cell therapy products.
根据ISBT(国际输血协会)的128项术语模型 (该模型针对标准分类)进行命名以区分所培养的间充质干细胞不同组织来源的细胞类型:骨髓间充质干细胞是MSC(M);脐带血间充质干细胞是MSC(CB);脂肪组织间充质干细胞是MSC(AT);脐带间充质干细胞是MSC(WJ)。
我们简单回顾一下, (ISCT)定义的间充质干细胞(MSC)的标准,包括:(1)贴壁细胞,(2)多系分化能力,可在体外分化成成骨细胞(Osteoblast)、脂肪细胞(adipocyte)、软骨细胞(chondrocyte)、肌细胞(myocyte)和其它结缔组织,(3)具有关键表面标志分子,包括:CD29、CD44、CD73、CD105和CD146,并且不具有如下的造血细胞表面标志分子:CD34、CD45、CD14、CD11b,CD79α,CD19和HLA-DR。
