    Abstract:
    Vascularization is a prerequisit for corpus luteum formation. Angiogenesis is supposed to be regulated by vascular growth factors. Vascular endothelial growth factor (VEGF) induces specifically endothelial cell proliferation as well as angiogenesis and increases capillary permeability. With this study we demonstrate for the first time the presence of VEGF-mRNA in human luteinized granulosa cells by Northern blot technique. Granulosa cells were obtained from 11 individual patients undergoing ovarian stimulation for in vitro fertilization procedure. Two transcripts of VEGF-mRNA at 3.9Kb and at 4.3Kb could be detected in each case. Specific transcripts were expressed in different amounts. These results indicate that VEGF may promote at least in part vascularization of the human corpus luteum.
