				        	Objective To study the expression of Survivin protein and its relation with the expression of Bcl-2, Bax in the tropho- blasts of human normal placenta. Methods The normal placental tissues (8 -9week ,18-23 week and 37-40week) were fixed, embed- ded, sectioned, and Survivin, Bcl-2, and Bax in the trophoblasts were detected with immunnohistochemistry. Result As the gestational age advanced , the staining intensity of Survivin in the trophoblasts was significantly decreased from the first trimester group to the second trimes- ter group to the term group (PU value: 11.74±0.8,9.95±0.43,8. 83 ~ O. 67, respectively, P <0.01 ), while the staining intensity of Bcl-2 and Bax in trophoblast was significantly increased (PU value of Bcl-2 : 4.33±0.60, 5.00±0.75,6.87±0.45, respectively, P<0.01 and PU value of Bax: 9.82±1.12,16.00±1.05,27.48±2.10, respectively, P <0.01 ). Expression of Survivin in trophoblasts has no rela- tionship with the expression of Bcl-2 and Bax (P>0.05 ). Conclusion Survivin may take part in the development of human normal pla- centa through the way of suppressing the apoptesis in trophoblasts. Expression of Survivin in trophoblasts has no relationship with the expres- sion of Bcl-2 and Bax, which indicate that they regulate apoptesis of trophoblasts via different biological pathways.
