【摘要】:目的通過(guò)遺傳眼病患者的外周血或皮膚組織建立永生化細(xì)胞系,以保存其遺傳資源。方法永生化B淋巴細(xì)胞系的建立:抽取患者靜脈血,分離淋巴細(xì)胞,以EB病毒體外轉(zhuǎn)化B淋巴細(xì)胞為類淋巴母細(xì)胞,利用環(huán)孢霉素A抑制T淋巴細(xì)胞RNA聚合酶Ⅱ活性,防止已轉(zhuǎn)化B淋巴細(xì)胞因受到T淋巴細(xì)胞的攻擊而退化,培養(yǎng)后建立永生化B淋巴細(xì)胞系;皮膚成纖維細(xì)胞原代培養(yǎng):利用DispaseⅡ酶處理離體皮膚組織以分離表皮組織,將其余組織剪碎后貼瓶培養(yǎng),成纖維細(xì)胞可從組織塊爬出,生長(zhǎng)成為細(xì)胞系。結(jié)果永生化B淋巴細(xì)胞系:共完成標(biāo)本17例,成功建系15例,成功率88.2%;經(jīng)過(guò)轉(zhuǎn)化后B淋巴細(xì)胞懸浮生長(zhǎng),胞漿豐富、形態(tài)各異,聚集成團(tuán),可無(wú)限傳代用于實(shí)驗(yàn)研究。皮膚成纖維細(xì)胞原代培養(yǎng):共完成標(biāo)本5例,成功建系3例,成功率60.0%;皮膚成纖維細(xì)胞貼壁生長(zhǎng),呈典型紡錘形,中間飽滿,兩邊細(xì)長(zhǎng),50代以內(nèi)增殖旺盛可用于實(shí)驗(yàn)研究。結(jié)論通過(guò)遺傳眼病患者的外周血和皮膚組織可建立永生化B淋巴細(xì)胞系和皮膚成纖維細(xì)胞系以保存其全部遺傳信息,為進(jìn)一步研究相關(guān)遺傳性眼病奠定物質(zhì)基礎(chǔ)。
