01General information

Description

MES-SA 是一种人类子宫肉瘤细胞系,来源于一名高级别子宫白肌瘤成年患者的胸腔积液。作为一种软组织肉瘤模型,MES-SA 显示出间质起源的特征,包括纺锤形形态和平滑肌肌动蛋白表达。MES-SA的细胞遗传学分析显示出复杂的核型异常,包括多种数字和结构染色体改变。重要的是,由于该细胞系对多柔比星敏感,而且有耐药亚系 MES-SA/Dx5,因此被广泛用于多药耐药性和化疗反应的研究。

MES-SA 具有野生型 p53 和视网膜母细胞瘤蛋白 (Rb),因此是研究 p53 能力背景下药物反应的有用工具。在各种功能基因组学和蛋白质组学筛选中,MES-SA 表现出信号转导通路参与的一致模式,尤其是涉及 PI3K/Akt 和 MAPK 通路的模式。反相蛋白质阵列分析证实了这些通路的活性,并揭示了与靶向治疗探索相关的蛋白质表达特征。此外,该细胞系已被纳入大规模药物基因组学资源(如癌症细胞系百科全书),并被用于药物敏感性、遗传依赖性和表观遗传修饰的综合分析。

最近对 MES-SA 染色质状态和基因调控的研究凸显了表观遗传学的脆弱性,特别是涉及启动子甲基化和组蛋白修饰模式。MES-SA 可作为组蛋白去乙酰化酶抑制剂和染色质修饰剂研究的模型系统。它被纳入反相蛋白质阵列和 DNA 甲基化数据库,进一步增强了其在临床前药物开发中的相关性,尤其是对肉瘤治疗药物的相关性。总之,MES-SA 为研究子宫肉瘤的分子基础和评估针对间质肿瘤的治疗策略提供了一个稳健且特征明确的平台。

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。
