01General information

Description

CASP-2-1细胞系是一种基因特征明确的小鼠前列腺上皮细胞系,通过组织重组方法从一种雄激素依赖性原发性肿瘤中建立而来。 CASP-2-1 属于 CASP 系列前列腺癌模型的一部分,该系列模型是通过将分离的胚胎泌尿生殖窦间充质与前列腺肿瘤上皮细胞进行重组而产生的,从而能够实现体内导管形成并验证上皮细胞的身份。 CASP-2-1 细胞表达 E-钙粘蛋白等上皮标志物,并在至少 30 代传代中表现出稳定的增殖能力,其致瘤能力通过体外无锚定生长和小鼠原位注射后的肿瘤形成得到证实。

CASP-2-1的一个显著特征是其保留了雄激素响应性。与其他几个CASP细胞系不同,CASP-2-1的生长依赖于雄激素,并在二氢睾酮(DHT)存在下表现出雄激素响应性启动子元件的激活。 该细胞系在mRNA和蛋白质水平上均表达野生型雄激素受体(AR),且未检测到AR突变。此外,CASP-2-1在Pten基因上呈杂合状态,并表现出中等水平的磷酸化Akt(p-Akt),表明PI3K/Akt信号通路部分激活。 这些特征使 CASP-2-1 成为解析前列腺癌中 AR 信号传导与 Pten 依赖性致癌通路之间相互作用的宝贵模型,特别是在早期或雄激素敏感性疾病背景下。

06Handling and culture

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

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。
