胎盘绒毛组织及脐血中造血细胞生长因子对人胎盘造血功能的影响

目的检测胎盘绒毛组织多种造血细胞生长因子(HGF)含量,探讨其对胎盘造血的意义。方法分别取早孕(6- 8周)、中孕(16-22周)、足月妊娠(37-42周)胎盘绒毛组织2 g各30份、脐血清30份,测定上清液中各种HGF含量。结果早期妊娠各种HGF均已产生;FL-13、IL-3在胎盘绒毛组织中含量随着胎龄增加,各胎龄组间比较,均有显著差异(P均< 0.01)。7种HGF在胎盘和脐血中含量,均有显著差异(P均<0.01)。结论F-T3配体(FL)、干细胞因子(SCF)、G-CSF等7 种HGF均参与胚胎期造血,尤以FL、IL-3、SCF最为重要。

Effect of Hematopoietic Growth Factors in Placenta Chorionic Villi and Umbilical Cord Blood on Placenta Hematopoiesis

Objective To study the role of hematopoietic growth factor(HGF)of placenta chorionic villus in fetal hematopoiesis during embryo ontogeny by observation of the appearance time and the content changes with the fetal growth, which was compared with HGF in cord blood. Methods Thirty embryo villus (2 g each) and 30 cord blood (2 mL each) were collected separately from early pregnant stage(6- 8 weeks), middle pregnant stage(16-22 weeks)and late pregnant stage (37-42 weeks). The levels of HGF were detected by enzyme - linked immunosorbent assay. Results HGF were produced on the early pregnant stage and the content of FL-T3,IL-3 increased gradually.There were significantly differences at different stages(P<0.01). All the contents of 7 HGF between embryo villus and the cord blood had significantly difference(all P<0.01).Conclusion All the 7 HGF play an important role in fetal hematopoiesis during embryo ontogeny,especially FL-T3 and IL-3.
