01General information

Description

Kera-308 细胞系由成年小鼠皮肤角质形成,是研究皮肤生理复杂过程,特别是伤口愈合和角质形成细胞功能的多功能模型。该细胞系在特定条件下(如用桑树根提取物处理)具有上调角蛋白表达(包括伤口诱导的角蛋白类型,如 Krt6a)的显著能力。Kera-308 细胞对磷酸-12-肉豆蔻酸 13-乙酸酯(PMA)的反应性突显了它们在研究皮肤修复和再生的细胞机制方面的作用。

Kera-308 细胞的一个突出特点是其增殖反应与剂量有关,在桑白根提取物等外部刺激下,增殖反应明显增强。这一特性使 Kera-308 成为探究角质形成细胞增殖和分化对治疗药物反应的分子基础的绝佳工具。

此外,Kera-308 细胞在伤口愈合情况下的转录特征,特别是其上调的角蛋白丝和 CXCL12/CXCR4 信号,为了解皮肤修复过程中的细胞和分子动态提供了宝贵的见解。这些信号通路的参与强调了 Kera-308 细胞在探索促进伤口愈合和治疗皮肤疾病的新治疗策略方面的相关性。

05Handling 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
Dissociation reagent
TrypLE Express(生命技术公司)
Subculturing
去除培养基,用不含钙和镁的 PBS 冲洗粘附的细胞(T25 细胞培养皿用 3-5 毫升 PBS,T75 细胞培养皿用 5-10 毫升)。加入 Tryple Express(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。37 度孵育 15 分钟。用 10 毫升培养基小心重悬细胞(必要时使用细胞刮刀),300xg 离心 5 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,使细胞从冷冻过程中恢复并至少贴壁24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.

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。
