01General information

Description

MCA-205是一种源自C57BL/6小鼠的纤维肉瘤细胞系。该细胞系最初通过甲基胆蒽诱导肿瘤发生建立,这是一种经典的化学致癌方法,广泛用于在同源小鼠中建立可移植肿瘤模型。 MCA-205作为免疫功能完整肿瘤模型,可无排异地移植至免疫功能完整的C57BL/6小鼠体内,因此特别适用于癌症免疫疗法和肿瘤免疫学的前临床研究。

从生物学角度看,MCA-205肿瘤被归类为非免疫原性或低免疫原性,这一特性反映其基线抗原性较低且不易发生自发性免疫介导排斥。该特征特别适用于评估检查点抑制疗法(如抗PD-1或抗CTLA-4)或肿瘤疫苗的疗效,其环境模拟了多种人类癌症的免疫逃逸特性。 尽管具有内在低免疫原性,MCA-205肿瘤在联合放疗、溶瘤病毒或TLR激动剂时可产生免疫调节反应,使其成为组合治疗测试的多功能平台。

MCA-205细胞在体外及体内均具快速增殖能力,皮下注射后可形成侵袭性纤维肉瘤。该肿瘤具有高度血管化特征,可支持可重复的肿瘤生长动力学,便于持续监测肿瘤负荷及治疗反应。 由于源自小鼠且与C57BL/6小鼠具有同源性,MCA-205细胞虽不适用于人类特异性检测,但在完整功能宿主免疫系统中探索免疫机制时不可或缺。

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.

05Quality 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。
