01General information

Description

CASP-1-1细胞系是一种经基因工程改造的小鼠前列腺上皮细胞模型,属于CASP系列的一部分,该系列是由小鼠原发性雄激素依赖性前列腺肿瘤建立的。 这些细胞是通过涉及泌尿生殖窦间质(UGM)的组织重组方法获得的,能够体内形成前列腺导管,从而证实了其上皮细胞的身份。 CASP-1-1 细胞表达 E-钙粘蛋白等上皮标志物,并通过体外锚定独立生长以及正位注射到小鼠前列腺后形成肿瘤,表现出致瘤潜力。这些细胞已实现永生化,在长期培养中保持稳定,已传代至少 30 次。

从遗传学角度看,CASP-1-1细胞的特征是Pten呈杂合状态(+/−),且显示中等水平的活化Akt(p-Akt),这反映了前列腺癌模型中常见的PI3K/Akt信号传导功能改变。 这些细胞中,雄激素受体(AR)在转录和翻译水平上均有表达,测序结果显示 AR 编码区未发现突变。 然而,尽管表达野生型 AR,CASP-1-1 却是雄激素非依赖性的,这意味着其增殖并不依赖于外源性雄激素,且在标准检测条件下不表现出雄激素响应性启动子活性。 这使得 CASP-1-1 特别适用于研究前列腺癌从雄激素依赖性向雄激素非依赖性的转变,以及 Pten/PI3K/Akt 和 AR 信号传导在此进展中的作用。

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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

07Quality control and cryopreservation

Freeze medium
作为冷冻保存培养基,我们使用完全生长培养基+10% DMSO,以获得足够的解冻后存活率。
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。
