摘要 目的:研究不同浓度瘦素(leptin)对人早孕期滋养细胞VEGF表达的调节作用。方法:行早孕期滋养细胞的原代培养;分别加入剂量为5ng/mL、50ng/mL、500ng/mL的leptin培养24h后,行RT-PCR检测滋养细胞VEGFmRNA的水平。结果:添加了leptin的滋养细胞分泌VEGF的量均较空白对照组有明显增加(P<0.01),其值(x±s)依次为0.13±0.02、0.23±0.03、0.21±0.02、0.45±0.04,且滋养细胞VEGF的分泌量呈现一定的量效关系。结论:单独提高leptin浓度能增强滋养细胞分泌VEGF的能力。早孕期滋养细胞分泌的VEGF对维系正常妊娠的顺利进行发挥了重要的作用,可能参与了妊娠的病理生理过程。
