01General information

Description

VCaP(前列腺癌椎体转移)细胞系是研究前列腺癌的一个重要模型,它来源于人类前列腺癌的椎体转移。建立它的目的是为研究前列腺癌的生物学特性及其转移过程提供一个相关的体外模型,特别是重点研究激素难治性阶段的前列腺癌。众所周知,VCaP 细胞表达高水平的前列腺特异性抗原(PSA)和雄激素受体(AR),这使它们与雄激素受体信号通路和抗雄激素疗法耐药机制的研究高度相关。

VCaP 细胞还被广泛用于基因研究,因为它们携带 TMPRSS2-ERG 基因融合,这是一种常见的染色体易位,在大约 50% 的前列腺癌病例中都能发现。这种特殊的基因改变被认为在前列腺癌的发展过程中起着至关重要的作用,因此意义重大。因此,VCaP 细胞是研究前列腺癌分子基础的绝佳工具,也是开发针对 TMPRSS2-ERG 和相关通路的新治疗策略的绝佳工具。此外,VCaP 细胞体外生长旺盛,异种移植到免疫缺陷小鼠体内可形成肿瘤,为临床前研究新型抗癌药物提供了有用的系统。

总之,VCaP 细胞系是分子和药理学研究的重要资源,对了解前列腺癌生物学特性和评估新的治疗药物大有裨益。VCaP细胞系具有激素反应性、基因融合表达和转移起源等特点,因此非常适合进行晚期前列腺癌研究,尤其是与雄激素独立性和转移性疾病进展相关的领域。

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。
