01General information

Description

AR42J 细胞是一种大鼠胰腺肿瘤细胞系,来源于阿扎塞林诱导的大鼠肿瘤。它们被广泛用作研究胰腺外分泌细胞功能、胰腺炎和胰腺癌的模型。AR42J 细胞具有类似胰腺尖塔的特征,因此在研究胰腺尖塔细胞的生理和病理方面特别有价值。

AR42J 细胞的一个显著特点是,当使用地塞米松或蛋白激酶 C 激活剂等各种药物时,它们能够分化成具有更明显胰腺外分泌功能的细胞类型。分化后,这些细胞会产生并分泌消化酶,包括淀粉酶、脂肪酶和糜蛋白酶,模拟正常胰腺尖突细胞的酶分泌特征。

AR42J 细胞还用于探索急性胰腺炎的发病机制。AR42J细胞会对胆囊收缩素类似物cerulein等刺激做出反应,而cerulein可诱导细胞出现类似急性胰腺炎的情况,其特点是酶过度分泌、氧化应激和炎症反应。这使得 AR42J 细胞成为测试胰腺炎潜在治疗干预措施的有用工具。

此外,AR42J 细胞系还被用于以胰腺癌为重点的研究,特别是肿瘤发生和尖突细胞恶性转化的研究。它们有助于研究癌基因、肿瘤抑制基因和生长因子对胰腺癌发生和发展的影响。

总之,AR42J 细胞为我们提供了一个多功能的动态模型系统,有助于加深我们对胰腺疾病的了解,并开发针对这些疾病的新治疗策略。

06Handling and culture

Culture medium
DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Subculturing
建议在细胞培养前用明胶覆盖组织培养瓶。在烧瓶中加入明胶,在 37 摄氏度下培养 30 分钟,然后用 PBS 冲洗一次。去除培养基,用不含钙和镁的 PBS 冲洗粘附的细胞(T25 细胞培养瓶用 3-5 毫升 PBS,T75 细胞培养瓶用 5-10 毫升 PBS)。加入 Accutase(每个 T25 细胞培养瓶 1-2 毫升,每个 T75 细胞培养瓶 2.5 毫升),细胞片必须完全覆盖。在环境温度下孵育 8-10 分钟。用培养基(10 毫升)小心重悬细胞,300xg 离心 3 分钟,用新鲜培养基重悬细胞,然后分装到装有新鲜培养基的新培养瓶中。
Seeding density
1 × 10⁴ 个细胞/平方厘米
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
解冻后,将细胞以5×10⁴个细胞/平方厘米的密度接种于培养皿中,让细胞从冷冻过程中恢复并至少贴壁48小时。
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。
