01General information

Description

MCA-3D 细胞系来源于小鼠表皮原代培养物,它们对钙诱导的末端分化具有抵抗力。这些细胞最初用致癌物质 N-甲基-N'-硝基-N-亚硝基胍(MNNG)或 7,12-二甲基苯并[a]蒽(DMBA)处理,随后暴露于 12-O-十四碳酰基樟脑-13-乙酸酯(TPA)。通过将培养基中的钙含量提高到 1.2 mM 来评估细胞对终极分化的耐受性,钙可选择性地促进转化细胞的生长,而正常细胞通常会发生终极分化并死亡。

MCA-3D 细胞系呈现上皮形态,并在培养过程中形成界限清晰的菌落。超微结构分析表明,MCA-3D 细胞含有角蛋白丝和脱丝体,这表明它们起源于上皮细胞,并在一定程度上维持了正常的角质细胞分化。然而,这些结构的确切丰度会因细胞系内不同亚群而有所不同。

MCA-3D 细胞通过皮下注射到合成的 Balb/c 新生儿体内进行了致瘤性测试,结果表明该细胞系即使在高钙条件下长期培养也不会致瘤。此外,MCA-3D 细胞在软琼脂中不生长,进一步证明了其非恶性表型。γ-谷氨酰转肽酶(GGT)活性和转谷氨酰胺酶活性的生化检测表明,MCA-3D 细胞的谷氨酰转肽酶(GGT)活性为阴性,其转谷氨酰胺酶活性与致瘤潜能无关,符合其非致瘤分类。

总之,MCA-3D 细胞系是研究癌变早期阶段以及影响从肿瘤前病变发展为完全恶性肿瘤的因素的模型。

05Handling and culture

Culture medium
Ham's F12,w:1.0 mM 稳定谷氨酰胺,w:1.0 mM 丙酮酸钠,w:1.1 g/L NaHCO3(Cytion 文章编号 820600a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Dissociation reagent
TrypLE Express
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 TrypleExpress(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 37 摄氏度下培养 15-20 分钟。用培养基(10 毫升)小心重悬细胞,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
0.5至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。
