Human endometrium is a mucosa served by a microvascular blood supply that involves benign angiogenesis under the control of ovarian steroids throughout reproductive life. Adrenomedullin is a multifunctional 52-amino acid peptide involved in numerous physiological and pathological processes, including angiogenesis, growth regulation, differentiation, vasodilation and smooth muscle relaxation. We have previously shown that adrenomedullin is present in the human uterus. To investigate further the role of adrenomedullin in human endometrial angiogenesis, a method for the isolation and culture of non-pregnant endometrial endothelium was developed. Enzymatic dispersion and 'Percoll' gradient centrifugation, followed by positive selection using Ulex europaeus agglutinin-coated immunomagnetic beads, yielded pure isolates of endothelium. The cells formed a typical 'cobblestone' monolayer within 5-7 days and expressed the classic endothelial markers, CD31 and von Willebrand factor. The presence of adrenomedullin immunoreactivity in endometrial endothelial cells was shown by immunohistochemistry both in vitro and in vivo. Adrenomedullin promotes growth of endothelial cells as measured by [methyl-(3)H] thymidine uptake. Adrenomedullin also induced cyclic AMP in endometrial endothelial cells. These results demonstrate, for the first time, that adrenomedullin is an autocrine growth factor for human endometrial endothelial cells and is thus involved in endometrial angiogenesis.
