Methods Human decidual tissues were taken from pregnant women of 6~ 8 weeks with induced abortions, then digested bycomplex enzyme and purified through severalnatural replication passages. The cellular morpholo2 gy was observed by inverted phase contrast microscope and the nucleus and cytoplasm were observed by staining ofhaema2 toxylin and eosin (HE). ecidual cellwas identified by the method ofimmunocytochemistryofprolactin (PRL). Cellcycle was observed by flow cytometry. Results The cultured cells appeared as fusiform or irregular astroform. Protein ofPRL was expressed in 95% cultured cell
