Abstract： 目的探讨人早孕绒毛组织中趋化因子CXCL16、CXCL12及其受体CXCR6、CXCR4的基因转录和蛋白表达特征.方法收集早孕绒毛组织并分离滋养细胞,采用半定量RT-PCR方法,检测人早孕绒毛滋养细胞(含绒毛滋养细胞和绒毛外滋养细胞)和人绒毛膜细胞癌细胞系JAR中CXCL16、CXCR6、CXCL12、CXCR4的基因转录水平;采用免疫组化和免疫细胞化学分析方法,检测人早孕绒毛滋养细胞及JAR细胞中CXCL16、CXCR6、CXCL12、CXCR4的蛋白表达.结果人早孕绒毛滋养细胞CXCL16、CXCR6、CXCL12、CXCR4的基因转录水平分别为0.89±0.11、1.12±0.25、0.78±0.10、1.08 ±0.11;JAR细胞CXCL16、CXCR6、CXCL12、CXCR4的基因转录水平分别为0.90±0.21、1.00±0.30、0.66±0.13、0.90±0.18,两者比较,差异无统计学意义(P＞0.05).CXCL16、CXCR6、CXCL12、CXCR4蛋白在人早孕绒毛滋养细胞和绒毛外滋养细胞中的表达均呈阳性.结论人早孕绒毛滋养细胞同时表达CXCL16、CXCL12、CXCR6、CXCR4,提示母-胎界面存在复杂的趋化因子调控网络,并参与调控滋养细胞自身的生物学行为.
