BioVector? MMNK-1是一種高度分化的永生化人膽管上皮細(xì)胞株。
來源: 人胎兒肝臟(OUMS-21)。
細(xì)胞類型: 永生化正常膽管細(xì)胞。
永生化方法: 通過轉(zhuǎn)導(dǎo) SV40 大T抗原 (SV40T) 和人端粒酶逆轉(zhuǎn)錄酶 (hTERT) 實現(xiàn)。
形態(tài): 上皮樣(epithelial-like)。
細(xì)胞標(biāo)志物: 表達(dá)膽管細(xì)胞特異性標(biāo)志物,包括 細(xì)胞角蛋白-7 (CK-7) 和 細(xì)胞角蛋白-19 (CK-19)。
功能特性:
在 Matrigel 實驗中可形成膽管樣管狀結(jié)構(gòu)。
經(jīng)脂多糖 (LPS) 處理后產(chǎn)生 白細(xì)胞介素-6 (IL-6)。
移植到免疫缺陷小鼠體內(nèi)后可發(fā)育出膽管樣結(jié)構(gòu)。
可逆性: 載體中含有 LoxP 位點(diǎn),通過 Cre 重組酶處理可切除 SV40T 基因,從而恢復(fù)非永生化表型。
培養(yǎng)基: 常用 DMEM 培養(yǎng)基,添加 5-10% 胎牛血清 (FBS)。
注:部分實驗室使用添加 EGM-2 補(bǔ)充因子的 MCDB-131 改良培養(yǎng)基。
傳代: 建議使用 Accutase 消化處理;倍增時間約 26-32 小時。
環(huán)境: 37°C,5% CO?。
限制: 原始寄托者通常不建議使用膠原涂層培養(yǎng)皿,因為可能會改變細(xì)胞特性。
BioVector? MMNK-1 is a highly differentiated, immortalized human cholangiocyte (bile duct epithelial) cell line.
Origin: Human fetal liver.
Cell Type: Immortalized normal cholangiocyte.
Immortalization Method: Transduction with SV40 Large T antigen and human telomerase reverse transcriptase (hTERT).
Morphology: Epithelial-like; exhibits highly differentiated characteristics of biliary cells.
Markers: Positive for cholangiocyte-specific markers, including Cytokeratin-7 (CK-7) and Cytokeratin-19 (CK-19).
Functional Traits:
Forms bile duct-like tubular structures in Matrigel assays.
Produces Interleukin-6 (IL-6) upon treatment with Lipopolysaccharide (LPS).
Forms bile duct-like structures when transplanted into immunodeficient mice.
Reversibility: Contains LoxP sites flanking the SV40T gene, allowing for reversion to a non-immortal phenotype upon treatment with Cre recombinase.
Medium: Typically cultured in specialized media such as modified MCDB-131 supplemented with EGM-2 SingleQuots (excluding ascorbic acid, which may be replaced by magnesium salt) and 2–10% FBS.
Passaging: Recommend using Accutase or 0.25% Trypsin; use a 1:10 to 1:20 split ratio.
Environment: 37°C in a 5% CO? atmosphere.
Vessels: Collagen-coated dishes are generally not recommended by the original depositor as they may alter cell characteristics.
