01General information

Description

HTh-7细胞系是一种人类未分化甲状腺癌(ATC)模型,广泛用于研究该恶性肿瘤的侵袭性特征。未分化甲状腺癌(ATC)的特征包括进展迅速、对常规治疗耐药以及预后不良。 HTh-7细胞表现出ATC典型的复杂染色体异常,包括与癌症进展相关的特定染色体区域(如20q染色体)的增益和缺失。这些细胞不携带常见的BRAF V600E突变——该突变在乳头状甲状腺癌中很常见,但在ATC中较少见,这凸显了不同甲状腺癌中致癌驱动因子的多样性。

对 HTh-7 细胞系的进一步基因组特征分析显示,TERT 启动子存在高频突变,这是侵袭性甲状腺癌的标志。这些细胞表现出野生型 TERT 拷贝的缺失,暗示存在纯合性 TERT 启动子突变,这很可能通过促进端粒酶激活而导致其侵袭性表型。 HTh-7细胞还携带TP53基因突变,导致p53功能完全丧失——这是ATC中的常见事件,也是基因组不稳定性的驱动因素。这种功能丧失常伴随其他突变,例如PTEN基因及参与PI3K/AKT/mTOR通路的基因突变,进一步凸显了Hth-7作为研究ATC分子机制模型的价值。

HTh-7细胞还表现出显著的去分化特征,这体现在其较低的甲状腺分化评分(TDS)上,与ATC肿瘤的情况相似。这种去分化是晚期甲状腺癌的特征,并体现在甲状腺特异性基因表达的严重缺失上,这使得HTh-7成为研究甲状腺癌去分化机制及相关治疗挑战的理想模型。 该细胞系的基因特征,包括TP53和TERT基因的突变,凸显了其在针对ATC探索新型治疗方法的临床前研究中的重要性,特别是针对端粒维持和p53相关机制的治疗策略。

05Handling and culture

Culture medium
RPMI 1640,w:2.1 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
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.

06Quality 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。
