1、大鼠肝細(xì)胞與Kupffer細(xì)胞共同培養(yǎng)對(duì)兩者功能和形態(tài)影響作者:寇晨光曹成波燕曉雯羅兵周巖冰【摘?!慷挠^察大鼠肝實(shí)質(zhì)細(xì)胞與Kupffer細(xì)胞體外共同培養(yǎng)吋對(duì)兩者生長(zhǎng)、形態(tài)及功能的影響。方法釆用原位二步IV型膠原灌注法>Percol1液密度梯度離心法分離Wistar大鼠肝實(shí)質(zhì)細(xì)胞與Kupffer細(xì)胞;體外將肝實(shí)質(zhì)細(xì)胞與Kupffer細(xì)胞按6:1比例共同培養(yǎng)。觀察不同情況下肝細(xì)胞生存時(shí)間和形態(tài),每隔24h檢測(cè)培養(yǎng)上清液屮清蛋白和谷丙轉(zhuǎn)氨酶(ALT).谷草轉(zhuǎn)氨酶(AST)的水平,并在培養(yǎng)36h用放免法檢測(cè)上清液中口細(xì)胞介素1(IL1)、口細(xì)胞介素6(IL6)、腫瘤壞死
