01General information

Description

NCI-H716 細胞系是一種源自結腸的人類腺癌細胞系。該細胞系是從一名 33 歲白人男性腹水中的轉移病灶建立而來。 NCI-H716 細胞系的顯著特徵之一,在於其能夠表達並分泌腸內分泌激素,尤其是胰高血糖素樣肽 1(GLP-1),這使其在腸道激素生理學及腸內分泌系統的研究中具有極高的相關性。 此特性對於糖尿病研究至關重要,特別是在探究胰島素分泌與血糖穩態的激素調控機制方面。

這些細胞能夠以浮游聚集体或懸浮培養的方式生長,這對於上皮來源的細胞而言頗為罕見。懸浮生長的能力使得研究人員能在三維培養環境中探究細胞間的相互作用與訊號傳導路徑,相較於傳統的單層培養,這種方式更能模擬體內環境。 NCI-H716 細胞系已被廣泛應用於探索參與激素分泌、對藥理學製劑的反應,以及腸上皮細胞與微生物群之間相互作用的訊號傳導途徑。 利用該細胞系進行的研究,對理解胃腸道疾病的病理生理機制,以及針對腸腦軸的治療策略開發,均做出了重大貢獻。

此外,NCI-H716 細胞還被用於測試治療化合物對分泌及受體反應的潛在影響。其獨特的激素表現型,也使其能應用於與代謝性疾病及肥胖症相關的藥效學研究與藥物發現。 因此,NCI-H716 作為轉譯醫學中不可或缺的工具,在胃腸道及代謝性疾病領域架起了基礎研究與臨床應用之間的橋樑。

05Handling 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
透過移液管上下吸放,輕柔地將燒瓶中的細胞懸浮液均質化,然後取一份具代表性的樣本,以測定每毫升的細胞密度。使用新鮮培養基將懸浮液稀釋至細胞濃度為 1 × 10⁵ 個細胞/毫升,並將調整後的懸浮液分裝至新的燒瓶中,以供進一步培養。
Seeding density
> 3 × 105 個細胞/毫升
Fluid renewal
每天添加 1 毫升新鮮培養基,週末可省略,並視需要使用移液管將菌落群分開。
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.

06Quality 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。
