01General information

Description

KU-19-19系人膀胱癌细胞系,源自一名患有转移性膀胱移行细胞癌的成年男性患者。该细胞系呈现上皮形态,在标准培养条件下表现为粘附生长。 研究表明,KU-19-19细胞系具有持续性分泌多种造血生长因子的特性,在体外展现出强劲的细胞因子分泌活性。其培养上清液能显著促进依赖生长因子的造血细胞系增殖,证实其具有生物活性细胞因子的功能性分泌能力。

生化分析证实KU-19-19培养上清液中粒细胞集落刺激因子(G-CSF)浓度高达5 ng/mL以上,同时可检测到粒单核细胞集落刺激因子(GM-CSF)、 巨噬细胞集落刺激因子(M-CSF)、干细胞因子(SCF)、白细胞介素-6(IL-6)及白细胞介素-8(IL-8)。 通过使用依赖细胞因子的白血病细胞系(包括髓系和巨核细胞模型)进行的功能增殖检测证实,KU-19-19衍生的因子能显著增强DNA合成(以胸苷掺入量为指标)。这种增殖反应呈剂量依赖性,并在多种造血细胞系中均有观察到,凸显了分泌因子的生物活性。

KU-19-19细胞的细胞因子产生受外部刺激调控。短期暴露于佛波酯(TPA)、白细胞介素-1β或干扰素-γ可导致G-CSF、GM-CSF和M-CSF分泌增加,表明多种调控信号通路共同控制该模型中的细胞因子表达。 这些特性使KU-19-19成为研究肿瘤来源细胞因子产生、肿瘤-造血细胞相互作用以及膀胱癌生长因子分泌调控的宝贵体外系统。

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。
