01General information

Description

HT-1197 是一种人类尿路上皮癌细胞系,从一名成年男性患者的膀胱高级别过渡细胞癌中提取。该细胞系来源于多次手术切除后复发的肿瘤,临床表现具有侵袭性,患者死亡前出现广泛转移。从形态上看,HT-1197 细胞具有上皮特征,包括在电子显微镜下观察到的微绒毛、肌纤维和脱钙小体的存在,这表明它们起源于尿路上皮。这些细胞在核型上与众不同,具有可识别的标记染色体,并能在软琼脂中生长,这是不依赖锚定生长的标志,而且在裸鼠和免疫抑制仓鼠中都具有致瘤性。

在分子水平上,HT-1197 存在与膀胱癌常见的几种关键致癌突变。它携带 FGFR3 中的活化 S249C 突变和 PIK3CA 中的 E545K 突变,这两种突变在尿路上皮性膀胱癌的发病机制中都很常见。此外,HT-1197 还存在 NRAS Q61R 突变和 TERT 启动子区突变,这表明其增殖能力和端粒酶活性增强。TP53状态包括c.1094A>G改变,进一步暗示了细胞周期控制和基因组稳定性的破坏。基因组分析表明,HT-1197 属于尿路上皮癌细胞系的一个亚群,其特点是基因组高度不稳定,分子特征与更具侵袭性的肌肉浸润性膀胱癌亚型一致。

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。
