01General information

Description

TCMK-1 是一種利用猿病毒 40 型(SV40)轉化而來的小鼠腎上皮細胞系。建立此細胞系旨在研究 SV40 在小鼠腎組織中誘導的細胞轉化與致癌作用。 轉化過程導致細胞形態發生改變、增殖能力增強,並具備在體外持續生長的能力。TCMK-1 細胞主要呈現上皮表型,其中夾雜部分紡錘形細胞及多核巨細胞,這些皆為轉化細胞系的常見特徵。

TCMK-1 的關鍵特徵之一是存在 SV40 大 T 抗原,該抗原透過失活 p53 和 RB 等腫瘤抑制蛋白,從而破壞正常的細胞週期調控。 此機制促使細胞不受控地分裂,並增強細胞存活能力。免疫螢光研究已證實 TCMK-1 細胞中存在 SV40 特異性抗原的表達,進一步證實了病毒誘導的轉化現象。此外,儘管這些細胞具有轉化特性,但當將其注射至免疫功能正常的鼠體內時,並未觀察到其形成腫瘤。

TCMK-1 已被應用於病毒致癌作用、腎細胞生理學及細胞轉化機制等相關研究。由於其具有 SV40 轉化特性,因此是研究病毒與宿主相互作用以及與細胞永生化相關分子途徑的有用模型。 然而,研究人員應留意,SV40 T抗原的存在可能影響正常細胞功能,進而影響實驗結果。

06Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS、10 mM HEPES、2.5 g/L 葡萄糖及 1 mM 丙酮酸鈉
Dissociation reagent
Accutase,於 37°C 下作用 10 分鐘
Subculturing
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫附。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。

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

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
