01General information

Description

WSU-HN6是一种源自上呼吸消化道肿瘤(具体为舌根部)的人类鳞状细胞癌(SCC)细胞系。该细胞系隶属于一套全面的头颈部鳞状细胞癌(HNSCC)细胞系库,旨在模拟此类癌症的生物学特性。 WSU-HN6在表征HNSCC常见分子改变方面发挥了关键作用,尤其涉及细胞周期调控和生长信号通路的改变。

该细胞系表现出周期素依赖性激酶(CDKs)活性升高,尤其是CDK4和CDK6,这与肿瘤抑制因子p16INK4A失活相一致。尽管许多HNSCC细胞系呈现周期素D1过表达,WSU-HN6却未出现此现象,表明其存在激活CDK的替代途径,如激酶过表达或负调控因子缺失。 此外,WSU-HN6虽表达野生型p53,却呈现细胞周期调控失常,暗示存在其他分子缺陷,包括p21功能或调控机制的潜在缺陷。

功能层面,WSU-HN6细胞呈现酪氨酸磷酸化水平升高,反映促进生长的受体酪氨酸激酶异常激活。该细胞系已证实表皮生长因子受体(EGFR)活性增强,但其EGFR蛋白过表达程度较同组其他细胞系相对温和。 WSU-HN6细胞系中的EGFR仍能响应配体刺激且功能完整。这些特征使WSU-HN6成为研究头颈部癌症中失调的生长信号传导和CDK通路异常的宝贵体外模型。

Supplements
在培养基中添加 10% FBS
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。
