01General information

Description

RLE-6TN 细胞系是一种永生化的大鼠肺泡 II 型上皮细胞系,来源于成年费舍尔 344 大鼠。RLE-6TN 是在尝试将 SV40-T 抗原基因导入原代肺泡 II 型上皮细胞的过程中通过自发永生化而建立的。与正转染 SV40-T 抗原的 RLE-6TN 细胞不同,RLE-6TN 细胞不表达 T 抗原基因。尽管如此,RLE-6TN 细胞仍保留了肺泡 II 型细胞的关键形态和功能特征,包括细胞角蛋白的表达和含脂片状包涵体的存在。

RLE-6TN 细胞已被广泛用作体外模型,用于研究肺上皮细胞生物学、肺泡功能以及对各种生理和病理刺激的反应。它们与研究肺泡上皮细胞中 Na-K-ATPase 的调节和活性尤其相关。Na-K-ATPase 对维持细胞离子梯度和跨上皮细胞离子转运至关重要,这些过程对肺泡液体的清除至关重要。研究表明,甲状腺激素(T3)通过增强 Na-K-ATPase 向质膜的转位而不是增加其转录来刺激 RLE-6TN 细胞中 Na-K-ATPase 的活性,这凸显了一种新颖、快速的调节机制。

RLE-6TN 细胞生长稳定,核型接近二倍体,对裸鼠无致瘤性。它们的碱性磷酸酶活性阴性,但细胞角蛋白 8、18 和 19 染色阳性,证实了它们的上皮来源。RLE-6TN 细胞可长期保持培养,是研究肺泡上皮修复、表面活性物质代谢以及细胞对肺损伤、毒素和治疗药物反应的可靠平台。

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。
