01General information

Description

JEG-3 细胞系来源于人类绒毛膜癌,这是一种源自胎盘滋养细胞的癌症。这些细胞具有滋养细胞的特征,包括能够产生激素,如对维持妊娠至关重要的人绒毛膜促性腺激素(hCG)。JEG-3 细胞属于上皮细胞,通常用于胎盘功能、癌症生物学和内分泌信号转导方面的研究。

众所周知,JEG-3 细胞具有侵袭性生长特点和侵入周围组织的能力,因此是研究滋养细胞肿瘤侵袭和转移机制的宝贵模型。此外,它们还被广泛用于研究胎盘发育的分子通路,以及滋养层细胞在妊娠期免疫耐受中的作用。滋养细胞通常在 RPMI-1640 培养基中培养,并补充胎牛血清和其他生长因子,以支持其增殖和维持。

该细胞系为研究胎盘癌症生物学、激素分泌以及滋养层细胞与母体免疫系统之间的相互作用提供了一个强大的平台。

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。
Seeding density
2×10⁴个细胞/cm²将在2至3天内形成融合单层。
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
让细胞从冷冻过程中恢复 24 到 48 小时。
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。
