RESULTS: The expression of AFP and Ha-ras, c-myc genes in the cultured oval cells from different phases was synchronous: At the beginning of oval cell cultivation in vitro, both of AFP and oncogenes displayed a higher level expression and then declined.
结果：AFP及c-ras、c-myc在卵圆细胞体外培养的不同时期呈现同步升高或降低：培养初期，卵圆细胞AFP及癌基因均呈高表达，而后下降；
