01General information

Description

SCLC-22H 细胞系是根据一名被诊断为燕麦细胞型小细胞肺癌(SCLC)(一种侵袭性肺癌亚型)男性患者的心包积液建立的。SCLC-22H 细胞系来源于一名小细胞肺癌(SCLC)患者,混合了典型和变异型 SCLC 的特征。这种中间性质使其成为研究这两种亚型之间过渡的宝贵模型。该细胞系显示出形态学特征,如小细胞和大细胞样特征,这些特征通常在小细胞肺癌和大细胞肺癌中都能看到,尤其是在异种移植中进行检查时。

SCLC-22H 表达多种神经内分泌标志物,包括神经元特异性烯醇化酶(NSE)、癌胚抗原(CEA)、蚕豆蛋白和肌酸激酶-BB(CK-BB),这些都是典型 SCLC 的标志物。然而,与关系密切的 SCLC-21H 细胞系相比,SCLC-22H 的群体倍增时间较慢,集落形成效率较低。这些生化和动力学特性将其与 SCLC-21H 区分开来,后者显示出更多以大细胞形态为主的变异亚型特征。

SCLC-22H 被认为是了解体内经典 SCLC 向变异 SCLC 演变的一个重要模型。其混合表型表明它代表了一个中间阶段或过渡阶段,为了解侵袭性肺癌的耐药性以及细胞形态和生长特征的变化提供了启示。

06Handling and culture

Culture medium
RPMI 1640,w:2.0 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
Subculturing
通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵细胞/毫升,并保持细胞浓度在1×10⁵至1×10⁶细胞/毫升范围内以获得最佳生长效果。
Seeding density

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
作为冷冻保存培养基,我们使用 50% 基础培养基 + 40% FBS + 10% DMSO 或 CM-1(Cytion 目录号 800100),其中包括优化的渗透保护剂和代谢稳定剂,以促进恢复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。
