1、胞分化、骨髓相关的树突状细胞分化、B细胞分化、T细胞分化、NK细胞分化、T细胞选择、淋巴相关的树突状细胞分化主要在肝再生早期、前期和后期进行;血管发生相关基因的Et05.144大于对照,推测血管发生在整个肝再生中都进行。分析神经细胞发生和分化及它的2条分途径相关基因协同作用(Et)表明,神经元发生和分化几乎在整个肝再生中都进行;神经胶质细胞发生和分化主要在肝再生早期、前期和后期进行。分析肌肉细胞发生和分化及它的3条分途径、上皮细胞发生和分化、脂肪细胞发生和分化相关基因协同作用(Et)表明,平滑肌细胞、上皮细胞发生和分化几乎在整个肝再生中都进行;横纹肌细胞、成肌细胞、
2、脂肪细胞发生和分化主要在肝再生早期、前期和后期进行。总之,在肝再生中这些细胞分化相互协调,调控再生肝中多类细胞的发生、增殖及再生肝的质和量。关键词:部分肝切除(PH);RatC论nome2302.O芯片;肝再生相关基因;细胞发生和分化;基因协同作用IIExpressionpattemsaIldactionanaIysisofgenesrelatedwimsiXkindsofcellgenesisanddif】’erentiationi11rat1iverregenerationAbstractMallyphysiologicaIa11dbiochemicalproc
