Previous studies have demonstrated that the human placental villi contain neuropeptideY (NPY), somatostatin (SS) and β-endorphin (β-EP) neuropeptidies, suggesting that theneuropeptides might play an important role in development of the placenta and feta. SP isa neuropeptide and was discovered earliest. It functions importantly in regulating bloodcirculation. But up to now, SP existing in human placenta has never been reported. Inthis experiment, we used immunohistochemical method and in situ hybridization at gene Previous studies have demonstrated that the human placental villi contain neuropeptide Y (NPY), somatostatin (SS) and β-endorphin (β-EP) neuropeptidies, suggesting that theneuropeptides might play an important role in development of the placenta and feta.
