01General information

Description

Capan-1 細胞系源自人類胰腺腺癌,是由一名 40 歲白人男性的腹水所建立。該細胞系於 1975 年首次被闡明其特性,其最顯著的特徵在於具有與原發性胰腺腫瘤極為相似的導管上皮形態。 Capan-1 細胞廣泛應用於旨在理解胰臟癌生物學的研究中,包括腫瘤進展、轉移及治療抗藥性的相關研究。該細胞系因能產生黏液(這是許多胰腺腺癌的特徵)而備受推崇,因此成為黏液性胰臟癌的模型。

從遺傳學角度來看,Capan-1 攜帶 KRAS 基因突變(此為胰臟癌的典型特徵),同時也存在其他與癌症相關基因(如 TP53 和 SMAD4)的變異。 這些突變使 Capan-1 細胞系成為研究胰臟癌分子機制,以及針對這些路徑的新型治療藥物進行臨床前評估的寶貴工具。此外,Capan-1 細胞亦被用於研究胰臟癌幹細胞的生物學特性,有助於深入了解驅動癌症復發及對傳統療法產生抗藥性的行為機制。

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)
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。
Seeding density
2 × 10⁴ 個細胞/cm² 將在約 7 天內形成 90% 融合的單層細胞
Fluid renewal
每 3 天
Post-thaw recovery
解凍後,將細胞以 5 × 10⁴ 個細胞/cm² 的密度接種於培養皿中,並讓細胞從冷凍過程中恢復,並附著至少 48 小時。
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。
