英文摘要：

Objective To search after a simple,convenient and practical method about in vitro primary cell culture of human trophoblast. Methods Tissue-culture method was used to get the primary human trophoblastic cells of first trimester pregnancy. The Ficoll separation and different speed adherence were used to purify the cells, immunocytochemistry with specific CK7 and Vimeintin monoclonal antibodies were used to identified the cells. Results The purification of obtained cells got to 95 %. Conclusion Tissue-culture, Ficoll separation and different speed adherence may be the effective method to culture the human trophoblast cell.
