01General information

Description

PM-LGSOC-01 是一种源自低级别浆液性卵巢癌(LGSOC)腹膜转移的细胞系。该细胞系是作为综合研究模型的一部分建立的,该模型还包括患者来源异种移植(PDX)。PM-LGSOC-01的建立是通过在SCID/Beige小鼠腹膜下注射肿瘤浆液进行正位移植,从而形成早期可移植腹膜转移(PM)-PDX模型。组织学分析证实,PM-PDX 和 PM-LGSOC-01 细胞都保留了 LGSOC 典型的微乳头状和楔形生长模式,肿瘤出芽,并表达 PAX8 和 WT1 等标记物。遗传分析表明,原发肿瘤、PM 和细胞系都有 KRAS c.35 G > T(p.Gly12Val)突变,因此该模型与研究 LGSOC 的进展和治疗反应相关,特别是与 MAPK 通路相关。

PM-LGSOC-01 具有与临床前研究相关的关键特征。在早期培养阶段,它的倍增时间约为 42 小时,而在细胞培养的后期阶段,倍增时间缩短到 23 小时,并已在体外培养阶段维持了 100 多次。该细胞系表现出上皮形态,具有上皮样组织和较高的细胞间粘附性。不过,它对铂类化疗的反应有限,但对紫杉醇高度敏感(IC50:6.3 ± 2.2 nM)。此外,PM-LGSOC-01 在体外和体内对 MEK 抑制剂曲美替尼(IC50:7.2 ± 0.5 nM)特别敏感,这反映了 KRAS 突变对治疗反应的影响。

PM-LGSOC-01是研究LGSOC的重要工具,特别是在耐药性、致瘤性以及对MEK抑制剂等靶向疗法的敏感性方面。鉴于低级别浆液性卵巢癌(LGSOC)与高级别浆液性卵巢癌(HGSOC)相比,对传统化疗的反应较差,因此将其用于开发低级别浆液性卵巢癌的个性化治疗方法至关重要。

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
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.

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。
