01General information

Description

WM-115系人源性黑色素瘤细胞系,源自成人皮肤恶性黑色素瘤患者的原发肿瘤。该细胞系由垂直生长阶段(VGP)原发病灶建立,属于一组特征明确的黑色素瘤模型系列,旨在代表黑色素瘤进展的不同阶段。 WM-115细胞在体外呈粘附生长,展现恶性黑色素细胞典型的上皮样至纺锤形形态。相关原发灶与转移灶的细胞遗传学分析证实存在非随机性染色体异常,尤其涉及1号、6号和7号染色体,支持黑色素瘤进展过程中的克隆进化。

表型上,WM-115细胞表达黑色素细胞谱系标志物及黑色素瘤相关抗原,包括色素沉着相关蛋白和细胞表面黏附分子。与非侵袭性放射状生长期病变相比,WM-115等垂直生长期黑色素瘤细胞对整合素和细胞外基质相关蛋白等黏附分子的表达显著增强,反映其侵袭潜能提升。 黑色素瘤细胞普遍表达胰岛素样生长因子-I等生长因子受体,并可变异性表达表皮生长因子受体家族成员,支持其通过自分泌和旁分泌机制促进生长。

功能上,WM-115细胞是垂直生长阶段出现转移能力的原发性黑色素瘤模型。 与需要多种外源性有丝分裂原才能增殖的正常黑色素细胞不同,WM-115 等原发性黑色素瘤细胞对外部生长因子的依赖性较低,在更宽松的培养条件下也能增殖。作为原发性肿瘤衍生的黑色素瘤模型,WM-115 被广泛用于研究黑色素瘤的进展、与侵袭相关的表型、生长因子信号传导以及与来自相同或相关患者的转移性黑色素瘤相比的治疗反应。

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

06Quality 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。
