实验步骤


一、气液界面(Air-Liquid Interface)3D培养

气液界面(ALI)3D细胞培养技术支持将人支气管上皮细胞从16HBE14o-等细胞分化为成熟的肺表型。使用ALI细胞培养技术培养的支气管上皮细胞可以形成极化细胞层和紧密连接,并且可以分化和呈现功能性纤毛。ALI细胞培养方法依赖于Millicell插入式细胞培养小室来支持体内观察到的假复层粘液纤毛表型的发展。

图1.在传统2D(左)与3D气液界面(ALI)(右)中培养的气道上皮细胞。

气液界面细胞培养方案

1. 用ECM混合物涂抹组织培养瓶:

 • 纤连蛋白 (FN) (10 μg/mL,F2006)

 • 胶原蛋白(30 μg/mL,5006)

 • BSA (100 μg/mL,126575) 在含有α-MEM(M2279)、 10% FBS (ES-009-B)、2mM L-谷氨酰胺(TMS-002-C)和1×青霉素-链霉素溶液(TMS-AB2-C)的ECM涂层烧瓶中培养和扩增 16HBE14o-细胞。不要让细胞在达到90-95%汇合后过度汇合和分裂。用胰蛋白酶-EDTA溶液(T3924)去除贴壁细胞。

2. 将16HBE14o-细胞接种以105个细胞/cm2 的密度接种到Millicell细胞培养小室 (MCHT12H48)中,将细胞浸入上述步骤1中列出的1-2mL扩增培养基中。将细胞在37°C的培养箱中培养24小时。

3. 启动气液界面培养,将培养小室/细胞转移到新的深12孔板(Greiner Bio-One ThinCert板)中。可以去除小室中的整个培养基,使细胞暴露在空气中。每2天更换一次小室背面外侧的培养基。

4. 在第8天或之后,可以使用常见的基于细胞的测定或抗体染色来分析细胞。

二、囊性纤维化细胞模型和CFTR功能

囊性纤维化是一种遗传性疾病,影响包括肺和消化系统等多个器官系统。这种疾病的特征是黏液分泌腺体异常,导致分泌物扰乱气道,粘稠的黏液堵塞肺部,可能导致死亡。囊性纤维化跨膜电导调节剂 (CFTR)蛋白有助于维持体内包括肺表面的盐水平衡。CFTR 基因的突变或缺失可导致囊性纤维化。

16HBE14o-细胞系 (SCC150) 是一种野生型气道上皮细胞系,可表达高水平的CFTR mRNA和蛋白质。亲本 CFBE41o-细胞系(SCC151)源自CF患者的ΔF508 CFTR突变纯合子。已创建该系的后续克隆,并校正了ΔF508 CFTR突变 (SCC158-SCC161)。

呼吸道病毒疾病机制(H1N1、SARS-COV、COVID-19)

支气管上皮细胞沿着进入肺部的主要通道构成功能屏障,构成抵御呼吸道病原体(包括流感 H1N1、SARS-CoV、MERS-CoV、RSV和COVID-19)的关键防线。16HBE14o 细胞系已用于研究和表征多种病毒感染机制,以支持疫苗和药物开发的研究。例如,16HBE14o-细胞表达血管紧张素转换酶2(ACE2)和丝氨酸蛋白酶 TMPRSS2,它们在SARS-CoV感染和病毒复制中起重要作用。
