01General information

Description

MRC-5 细胞是一种人类肺成纤维细胞系,1966 年从一个 14 周大的男性胎儿的肺组织中提取,被广泛用于生产某些疫苗,包括甲型肝炎疫苗、脊髓灰质炎疫苗、狂犬病疫苗等。

MRC5 细胞对各种人类病毒,特别是人类脊髓灰质炎病毒 1、单纯疱疹病毒和水泡性口炎病毒的易感性突出表明了 MRC5 细胞在发现抗病毒药物、病毒疫苗、疫苗安全性和病毒复制方面的作用。如今,MRC-5 和 WI-38 细胞系仍被用于生产水痘、风疹、甲型肝炎疫苗和狂犬病疫苗。最近,MRC-5 细胞被改造为表达 ACE2 受体,成为 SARS 研究的关键。通过改造 MRC5 人类 ACE2 细胞,科学家们可以研究 SARS-CoV 病毒如何进入宿主细胞并在其中复制。这项工作对于了解病毒的行为以及开发有针对性的抗病毒药物和治疗方法至关重要。

MRC5 胎儿细胞系的用途不仅限于疫苗生产,还包括在癌症研究中的潜在作用,由于该细胞系能够分化成多种细胞类型,包括骨细胞和软骨细胞,因此被用于探索肿瘤微环境和癌细胞相互作用的研究。这也让人们猜测它们与间充质干细胞(MSCs)的相似性,因为它们具有类似成纤维细胞的形态,而且在体外大量扩增后仍能保持正常的二倍体核型。

06Handling and culture

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。

为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
