We also observed the cell - cell contact through the pseudopod 相邻细胞伸长的伪足相互连接。

We examined the cells began to adhere 12 hr after the cells inoculated . the pseudopod were determined at 48 hr of culture . these cells adhered displayed typical epithelial cells morphological characteristics : the hepatocytes had a rich cytoplasm and were sometimes binucleate 用含10新生牛血清的rpmi1640培养液进行培养， 12h后细胞开始贴壁生长， 48h伸出伪足，呈现典型的上皮样细胞的外形形态，胞浆内有空泡和脂滴，可以见到双核细胞。
