01General information

Description

HCE-T 是一种源自原代人角膜上皮的 SV40 转化人角膜上皮细胞系。该细胞系通过感染重组 SV40-腺病毒杂合载体(Ad–SV40)建立,从而能够稳定表达 SV40 大 T 抗原并持续增殖。最初的特征鉴定工作旨在特异性地建立一种能够持续增殖且不释放游离病毒颗粒的角膜上皮细胞系。

在体外培养中,HCE-T 细胞呈现典型的上皮“鹅卵石”形态,并以贴壁单层形式生长。 已有研究报道其具有桥粒和顶端微绒毛等超微结构特征,且该细胞被证实可产生一种与角膜相关的64 kD角蛋白。在适当的分化条件下(例如在胶原蛋白上的气液界面培养),HCE-T细胞可形成多层分层结构并发展出可测量的屏障特性,这支持将其应用于眼表研究。

HCE-T细胞被广泛用于研究角膜上皮屏障功能、通透性及制剂效应、迁移/修复相关过程,以及细胞对炎症或刺激性因子的反应。然而,其转运蛋白表达模式和分化标志物谱可能与天然人类角膜以及原代角膜缘/角膜上皮系统存在差异。 因此,HCE-T 最适合用于机制性和比较性体外研究,而将其结果直接定量外推至体内人类角膜吸收或角膜分化生物学时,应谨慎行事。

06Handling and culture

Culture medium
DMEM:Ham's F12(1:1),w: 3.1 g/L 葡萄糖,w: 2.5 mM L-谷氨酰胺,w: 15 mM HEPES,w: 0.5 mM 丙酮酸钠,w: 1.2 g/L NaHCO3(Cytion 文章编号 820400a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 5% FBS、1% ITS(0.625 毫克/毫升人胰岛素、0.625 毫克/毫升人转铁蛋白、0.625 微克/毫升亚硒酸钠、0.535 毫克/毫升亚油酸、125 毫克/毫升 BSA)和 10 纳克/毫升人表皮生长因子。
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。
