01General information

Description

CEM/C1细胞系是CCRF-CEM人类T细胞白血病细胞系的衍生物,专门针对其对某些化疗药物(特别是拓扑异构酶II抑制剂多柔比星)的耐药性进行筛选。这种选择使该细胞系在多药耐药性研究中具有重要的应用价值,多药耐药性是治疗各种癌症过程中普遍面临的挑战。CEM/C1 细胞系过量表达 MDR1 基因,该基因编码 P 糖蛋白,而 P 糖蛋白是细胞对化疗药物产生耐药性的关键外排转运体。

从遗传学角度看,CEM/C1 细胞具有人类 T 淋巴细胞系的特征,因此与 T 细胞生物学和白血病研究高度相关。这些细胞保持着旺盛的增殖能力,可用于体外实验,以了解耐药性、细胞凋亡和新化疗药物疗效的细胞机制。这些细胞还为药理学研究,特别是在受控实验环境下评估抗癌药物的药效学和药代动力学提供了宝贵的工具。

由于具有耐药性,CEM/C1 细胞在开发规避或直接针对耐药机制的治疗策略方面特别有用。利用这种细胞系进行的研究有助于人们更广泛地了解癌细胞的生存策略,并有可能开发出更有效的癌症疗法,尤其是针对难治性或复发性 T 细胞白血病的疗法。

05Handling 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% 热灭活 FBS
Subculturing
通过上下吸取操作轻柔匀化烧瓶中的细胞悬液,随后取代表性样本测定每毫升细胞密度。用新鲜培养基将悬液稀释至1×10⁵细胞/毫升浓度,并将调整后的悬液分装至新烧瓶中进行后续培养。
Fluid renewal
每周 2 至 3 次
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。
