01General information

Description

HEL 92.1.7细胞系具有自发分化成类红细胞的能力,在体外模拟了红细胞成熟的某些方面。这一特性使它们特别适用于研究红细胞分化过程以及与红细胞生成有关的基因表达调控。它们的自发分化能力为研究驱动红细胞前体成熟的内在途径和机制提供了独特的优势,而无需添加外部分化诱导剂。

此外,HEL 92.1.7 细胞的分化还可以通过添加磷酸酯(如 TPA(12-O-十四碳酰基-phorbol-13-acetate)和 PMA(phorbol myristic acid))来进一步操纵。这种诱导的巨噬细胞样分化将 HEL 92.1.7 细胞系的用途扩展到红细胞研究之外,使研究人员能够探索和了解造血细胞的可塑性,以及在何种条件下可重新定向血系承诺和细胞特性。此类研究对于开发旨在操纵细胞命运的治疗策略至关重要,可用于再生医学和癌症治疗。

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% 热灭活 FBS
Dissociation reagent
Accutase
Subculturing
将悬浮细胞收集到 15 毫升试管中,用不含钙和镁的 PBS(T25 烧瓶用 3-5 毫升,T75 烧瓶用 5-10 毫升)轻轻清洗粘附的细胞。涂抹 Accutase(T25 烧瓶 1-2 毫升,T75 烧瓶 2.5 毫升),确保完全覆盖细胞层。让细胞在室温下孵育 10 分钟。孵育后,将悬浮细胞和粘附细胞混合并离心。离心后,小心重悬细胞团,并将细胞悬浮液转移到装有新鲜培养基的新烧瓶中。

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。
