01General information

Description

D341 Med 细胞系是弗里德曼等人于 1988 年从一名被诊断患有髓母细胞瘤的 3 岁男孩身上提取的肿瘤组织中建立的。髓母细胞瘤是一种高度恶性的小儿脑肿瘤,主要发生在小脑。这种细胞系对研究至关重要,因为它源自一种常见的儿童脑癌,能让人们深入了解儿科病例特有的肿瘤生物学和遗传学。D341 Med 已被广泛用于旨在了解髓母细胞瘤的分子和细胞机制的研究,包括调查导致肿瘤发生和治疗耐药性的基因突变和信号通路。

除了在基础研究中发挥作用,D341 Med 细胞系在评估髓母细胞瘤新疗法的临床前研究中也发挥了重要作用。它的遗传特征反映了人类肿瘤中常见的改变,是评估潜在药物和新型治疗策略疗效的绝佳模型。在这些研究中使用 D341 Med 有助于弥合实验室研究与临床应用之间的差距,支持靶向疗法的开发,从而改善受这种毁灭性疾病影响的儿童的治疗效果。

05Expression and susceptibility

Protein expression
谷氨酰胺合成酶阳性、神经元特异性烯醇化酶阳性、胶质纤维酸性蛋白阴性、S100(S-100)蛋白阴性、神经外胚层抗原阳性,可被 UJ13A 单克隆抗体识别

06Handling and culture

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
Subculturing
通过上下吸取操作轻柔匀化烧瓶中的细胞悬液,随后取代表性样本测定每毫升细胞密度。用新鲜培养基将悬液稀释至1×10⁵细胞/毫升浓度,并将调整后的悬液分装至新烧瓶中进行后续培养。
Fluid renewal
每周 2 至 3 次
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。
