01General information

Description

TOV-21G 是一种人上皮性卵巢癌细胞系,源自一名未曾接受过化疗或放疗的成年患者的原发性透明细胞癌肿瘤。该细胞系作为一组自发永生化卵巢癌模型的一部分而建立,这些模型保留了其来源原发肿瘤的许多生物学特征。 TOV-21G 在培养中呈贴壁上皮单层生长,其形态学和分子特征与透明细胞卵巢癌一致。透明细胞卵巢癌是上皮性卵巢癌中一种独特的组织学亚型,以侵袭性临床行为和独特的分子改变为特征。

对卵巢癌细胞系系列的分子和基因组分析表明,TOV-21G 含有与卵巢肿瘤发生密切相关的基因和通路改变,包括影响肿瘤抑制基因和细胞周期调节通路的突变。 利用高密度微阵列进行的基因表达谱比较显示,TOV-21G 表现出与正常卵巢表面上皮细胞截然不同的转录模式,且更接近于侵袭性上皮性卵巢肿瘤中观察到的表达谱。这些分析突显了参与增殖、细胞信号传导和肿瘤进展的众多基因的失调,从而证实了 TOV-21G 作为研究卵巢癌生物学模型的相关性。

利用TOV-21G进行的功能研究证实,其在实验系统中表现出显著的肿瘤特性,包括锚定独立生长、侵袭行为及致瘤潜能。 染色体和基因组研究进一步表明,引入特定的正常染色体(如第6号或第18号染色体)可抑制部分恶性表型,这暗示存在影响卵巢癌进展的肿瘤抑制基因位点。这些特性使TOV-21G成为研究卵巢癌发生机制、肿瘤抑制基因功能以及评估透明细胞卵巢癌靶向治疗策略的宝贵实验模型。

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。
