01General information

Description

GH3 细胞系源自大鼠垂体瘤,是研究垂体功能,尤其是催乳素和生长激素分泌的重要资源。这些细胞同时具有促体液细胞和促泌乳细胞的特征,可以对垂体激素及其调控机制进行详细研究。该细胞系被广泛用于了解激素治疗和基因修饰对这些激素分泌的影响。GH3 细胞对甲状腺刺激激素有明显的反应,因此是测定各种化合物对垂体活动影响的重要模型。

利用 GH3 细胞进行的研究通常会探讨这些细胞如何对不同的激素刺激做出反应。例如,氢化可的松可促进生长激素的分泌,同时抑制催乳素在这些细胞中的输出,因此 GH3 细胞是探索激素平衡以及内分泌系统对压力和其他生理因素反应的首选模型。这些研究对于加深我们对垂体疾病的了解,以及针对生长缺陷和高催乳素血症等病症制定治疗方法至关重要。

此外,GH3 细胞还有助于药理测试和生物技术应用,以开发治疗垂体相关疾病的方法。与 GH1 细胞相比,GH3 细胞能够产生更多的生长激素和催乳素,这使研究人员能够研究这些激素在不同条件下的调节和影响。这种独特的特征对于了解内分泌系统内部复杂的相互作用以及开发有针对性的治疗干预措施至关重要。

06Handling and culture

Culture medium
Ham's F12K 培养基,w:2.0 mM L-谷氨酰胺,w:2.0 mM 丙酮酸钠,w:2.5 g/L NaHCO3(Cytion 文章编号 820608a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
用 15%马血清、2.5% 热灭活 FBS 补充培养基
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。
