靜/動(dòng)態(tài)培養(yǎng)模式對(duì)CIK細(xì)胞體外擴(kuò)增與代謝特性的影響及其機(jī)制
發(fā)布時(shí)間:2021-11-18 14:46
過繼性免疫細(xì)胞療法是一種非常有前景的腫瘤疾病治療手段。細(xì)胞因子誘導(dǎo)的殺傷細(xì)胞(Cytokine induced killer,CIK)是過繼性免疫細(xì)胞療法中常用的效應(yīng)細(xì)胞之一,基于CIK細(xì)胞的免疫細(xì)胞療法目前在多種腫瘤疾病的臨床治療中取得了積極的成果,具有廣闊的應(yīng)用前景。由于細(xì)胞治療的效果與輸注細(xì)胞的數(shù)量和質(zhì)量密切相關(guān),因此是否能在短時(shí)間內(nèi)獲得足夠數(shù)量且具有高抗腫瘤活性的CIK細(xì)胞是決定該療法能否取得預(yù)期療效的關(guān)鍵環(huán)節(jié)之一。目前CIK細(xì)胞的體外制備過程通常是采用培養(yǎng)袋進(jìn)行靜態(tài)培養(yǎng),但該培養(yǎng)模式由于混合效果和氣液傳質(zhì)能力差,容易使?fàn)I養(yǎng)物或代謝副產(chǎn)物產(chǎn)生濃度梯度,導(dǎo)致培養(yǎng)環(huán)境不均一且難以控制,不僅影響細(xì)胞擴(kuò)增的效果以及所獲得CIK細(xì)胞的功能,也使得擴(kuò)增工藝過程難以重復(fù)。為解決這一問題,本文嘗試建立CIK細(xì)胞的動(dòng)態(tài)培養(yǎng)技術(shù),期待通過良好的混合解決培養(yǎng)環(huán)境不均一的問題,通過增加物質(zhì)傳遞提高營(yíng)養(yǎng)物的利用效率,從而實(shí)現(xiàn)CIK細(xì)胞的高效擴(kuò)增,為將來(lái)建立基于生物反應(yīng)器的CIK細(xì)胞或其它免疫效應(yīng)細(xì)胞的高效規(guī);瘮U(kuò)增技術(shù)提供技術(shù)支撐。本文采用有血清培養(yǎng)體系以臍帶血單個(gè)核細(xì)胞(Cord blood mono...
