01General information

Description

KLE 細胞系是一種源自一名患有腺癌的白人女性患者子宮內膜的黏附性細胞系。該細胞系是從一名孕齡 64 天的患者身上建立的,此後已成為子宮內膜癌研究中不可或缺的工具。 KLE 細胞由 G. R. Richardson 寄存,以其致瘤性著稱,當將其皮下接種至裸鼠體內時,21 天內形成腫瘤的發生率達 100%。 這些腫瘤雖不形成腺體,但呈現微絨毛、連接複合體及核仁通道系統,其特徵與受黃體素刺激下的正常子宮內膜所見相似。

KLE 細胞表現 O 型血型且為 Rh 陽性,這對於涉及抗原表現的特定研究可能具有相關性。該細胞系常被用於研究子宮內膜癌的病理生理學,其中其雌激素受體陰性與黃體酮受體陽性的特徵尤受關注。 這種受體特徵使 KLE 細胞非常適合用於研究黃體酮在子宮內膜癌進展中的作用。針對 KLE 細胞衍生的腫瘤所進行的電子顯微鏡研究,已提供了關於細胞超微結構的詳細見解,使該細胞系成為理解子宮內膜腺癌形態學方面的關鍵資源。

06Handling and culture

Culture medium
DMEM:Ham's F12(1:1),重量比:3.1 g/L 葡萄糖,重量比:2.5 mM L-谷氨酰胺,重量比:15 mM HEPES, w: 0.5 mM 丙酮酸鈉,w: 1.2 g/L NaHCO₃(Cytion 產品編號 820400a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Dissociation reagent
Accutase
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。
