01General information

Description

16HBE140 細胞系源自人類支氣管上皮細胞,對於研究呼吸道上皮至關重要。 這些細胞保留了原代支氣管上皮細胞的多項關鍵特徵,包括形成緊密連接的能力、表達特徵性標記物,以及展現典型的上皮形態。它們廣泛應用於呼吸系統疾病、藥物轉運及毒理學研究,為理解支氣管上皮細胞在各種條件下的行為提供了可靠的體外模型。

16HBE140 細胞的一項重要應用在於囊性纖維化(CF)的研究,這是一種影響呼吸系統的遺傳性疾病。這些細胞會表達囊性纖維化跨膜傳導調節蛋白(CFTR),使其成為研究 CF 病理生理學及篩選潛在治療藥物的寶貴工具。 此外,鑑於 16HBE140 細胞會對促炎性細胞因子及污染物產生反應,因此亦被應用於氣道發炎研究,有助於理解哮喘及慢性阻塞性肺病(COPD)等慢性呼吸道疾病。

GMO status details
GMO-S1: This human bronchial epithelial cell line (16HBE14o-) carries a non-replicating pSVori-based construct expressing the SV40 Large T Antigen from Macaca mulatta polyomavirus 1, enabling extended proliferation through interference with cell-cycle control. The insert is stably present in primary-derived human bronchial epithelial cells. This classification applies only within Germany and may differ elsewhere.

06Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 馬血清和 1% NEAA
Dissociation reagent
Accutase
Flask coating
基於 LHC 基礎培養基的塗層溶液:0.01 毫克/毫升 人源纖維連接蛋白、0.1 毫克/毫升 牛血清白蛋白(BSA)
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。
