摘要:

通过体外培养获得高质量的肌腱来源间充质干细胞,为运动性损伤治疗、竞赛马运动性损伤治疗、诸多疾病的治疗、单细胞测序、多组学研究、基因组文库构建、cDNA文库构建、线粒体DNA文库构建和基因功能等诸多方面的研究提供种子细胞,具有重要的深入研究价值。本研究选取63只26日龄,平均体重40.3 g,雄性健康北京鸭胎鸭骨骼肌肌腱为研究对象,利用Ⅳ型胶原酶消化法和组织块贴壁培养法在体外进行肌腱来源间充质干细胞培养,同时按照国际细胞质量检测内容和标准对所培养的体外培养细胞进行了全面的质量检测。通过肌腱来源间充质干细胞的形态学、冻存前活率、微生物污染(细菌、真菌、原虫、支原体和病菌)、阳性率、克隆能力、迁移能力、表面标志物反转录PCR、冻存复苏后形态、冻存后活率、生长曲线绘制和群体倍增时间、免疫组织化学、核型、多向诱导分化潜能(向成脂细胞诱导分化能力、向成骨细胞诱导分化能力和向成软骨细胞诱导分化能力)等20项质量检测结果表明,所建细胞系均达到国际优质细胞标准。通过大量的重复试验证明,已建立了用于治疗运动性损伤肌腱来源间充质干细胞体外培养和鉴定的科学体系,并获得了大量的高质量供体细胞,为成功构建治疗运动性损伤医学模型,以及动物学、畜牧学和医学等生命科学领域的相关研究奠定了理论、方法、技术和实物基础。

Abstract:

Obtaining high-quality tenogenic mesenchymal stem cells(MSCs) through in vitro culture, providing seed cells for the treatment of sports injuries (including equine athletic injuries), various diseases, single-cell sequencing, multi-omics research, genomic library construction, cDNA library construction, mitochondrial DNA library construction, gene function research and other investigations, had important in-depth research value. In this study, tendon tissues were collected from the skeletal muscles of 63 healthy male Peking duck embryos at 26 days of age (average weight: 40.3 g). Tenogenic MSCs were isolated and cultured in vitro using the type Ⅳ collagenase digestion method and the tissue block adhesion culture methods. Meanwhile, comprehensive quality assessment of the cultured cells in vitro were conducted according to international cell quality inspection standards and parameters. The results of 20 quality tests, including cellular morphology, pre-cryopreservation viability, microbial contamination (bacteria, fungi, protozoa, mycoplasma, viruses), positive marker expression, clonogenic capacity, migration ability, post-thaw morphology, post-thaw viability, growth curve analysis, population doubling time, reverse transcription PCR (RT-PCR) for surface markers, immunohistochemistry, karyotype analysis, and multidirectional differentiation potential (adirogenic, osteogenic, and chondrogenic induction), indicated that all established cell lines met international standarda for high-quality cells. Through a large number of repeated experiments, a scientific system for the culture of tenogenic MSCs in vitro for sports injuries therapy has been established, and a substantial quantity of high-quality donor cells has been acquired. This achievement lays a solid theoretical, methodological, technical, and material foundation for successfully constructing medical models for sports injury treatment, as well as for related research in zoology, animal science, veterinary medicine, and the broader life sciences.

Key words: mesenchymal stem cells, culture and identification, treatment of sports injuries
