01General information

Description

SCLC-22H 細胞系是從一名被診斷為燕麥細胞型小細胞肺癌(SCLC)的男性患者的心包積液中建立的,該類型屬於肺癌中侵襲性較強的亞型。 源自小細胞肺癌(SCLC)患者的 SCLC-22H 細胞系,同時具備經典型與變異型 SCLC 的典型特徵。這種中間性質使其成為研究這兩種亞型之間轉變的寶貴模型。 該細胞系呈現出小細胞和大細胞樣等形態學特徵,這些特徵通常見於小細胞肺癌和大細胞肺癌,特別是在異種移植模型中觀察時更為明顯。

SCLC-22H 表達多種神經內分泌標記物,包括神經元特異性烯醇化酶(NSE)、癌胚抗原(CEA)、邦貝辛(bombesin)及肌酸激酶-BB(CK-BB),這些皆為經典型小細胞肺癌的標誌性特徵。 然而,與密切相關的 SCLC-21H 細胞系相比,SCLC-22H 的細胞群倍增時間較長,且集落形成效率較低。這些生化與動力學特性使其有別於 SCLC-21H——後者展現出更多變異亞型的特徵,且以大細胞形態為主。

SCLC-22H 被視為理解體內從經典型小細胞肺癌(SCLC)進展至變異型小細胞肺癌(SCLC)過程的重要模型。其混合表型暗示該細胞系代表一種中間或過渡階段,有助於深入了解在侵襲性肺癌中,治療抗藥性以及細胞形態與生長特徵的變化是如何發展的。

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% 的胎牛血清(FBS)
Subculturing
透過定期添加或更換培養基來維持培養。起始培養時,細胞密度應為 5 × 10⁵ 個細胞/毫升,並將細胞濃度維持在 1 × 10⁵ 至 1 × 10⁶ 個細胞/毫升的範圍內,以達到最佳生長效果。
Seeding density
1 × 105 個細胞/毫升
Fluid renewal
每週 1 至 2 次
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 50% 基礎培養基 + 40% 胎牛血清 (FBS) + 10% 二甲基亞砜 (DMSO),或 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,可提高細胞存活率並減輕冷凍引起的應激。
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。
