01General information

Description

PC-3M 细胞系是从人类前列腺腺癌 PC-3 细胞系衍生出来的转移变种,最初是从一名前列腺癌患者的骨转移瘤中分离出来的。PC-3M 的建立是为了更好地模拟前列腺癌的转移潜能。与亲代相比,该细胞系具有更强的迁移和侵袭能力,是研究转移的分子机制和评估针对转移性前列腺癌的治疗干预的重要工具。

PC-3M 细胞已被用于各种体外和体内研究,以调查肿瘤进展和治疗耐药机制。PC-3M细胞对各种培养条件都有很强的适应性,在标准培养和动物模型中都表现出强劲的生长能力。值得注意的是,PC-3M 株系已被广泛应用于异种移植研究,它具有形成肿瘤和高效转移的能力,复制了晚期前列腺癌的关键特征。这使其成为测试抗转移药物和阐明驱动转移扩散途径的宝贵模型。

除了转移特性外,PC-3M 还被用来探索肿瘤细胞与微环境之间的相互作用,包括基质细胞和细胞外基质成分在促进癌症进展中的作用。该细胞系还能表达与前列腺癌相关的生物标记物,如前列腺特异性抗原(PSA),并可进行基因组和蛋白质组分析,使研究人员能够研究分子通路并确定潜在的治疗靶点。

05Handling and culture

Culture medium
Ham's F12K 培养基,w:2.0 mM L-谷氨酰胺,w:2.0 mM 丙酮酸钠,w:2.5 g/L NaHCO3(Cytion 文章编号 820608a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
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。
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。
