On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

Through primary analysis on the characteristics of ammonifiers growth and function, ammonification is a possibly important origin of ammonia in Suzhou Creek water body. The studies tested that adding K2HPO4 can reduce ammonifiers function. It maybe has important reference value for ecosystem resume in Suzhou Creek.

通过对苏州河氨化菌的生长特性和功能活性的初步分析，氨化作用可能是氨氮的重要来源之一，研究还表明，添加磷酸氢二钾可以降低苏州河氨化菌的转氨活性，原理尚不清楚，对苏州河的生态恢复可能具有重要的参考价值。
