Danzhi decoction significantly lowered VEGF-A/C/D levels in a 3D co-culture model of pelvic inflammatory disease sequelae, potentially by targeting endometrial glandular epithelial cells.

Abstract

OBJECTIVE: To investigate the effects of traditional Chinese medicine, Danzhi decoction, on the expression angiogenesis factors in human endometrial cells during the sequelae of pelvic inflammatory disease (SPID) and explore the role of Danzhi decction in improving the blood stasis microenvironment of SPID. METHODS: A three-dimensional (3D) co-culture system including human vascular endothelial cells (VECs), endometrial stromal cells and glandular epithelial cells was established in vitro and treated with Danzhi decoction, sterilized water and aspirin respectively. A Milliplex multifunctional liquid chip technique was used to measure the expression levels of vascular endothelial growth factor (VEGF)-A/C/D, fibroblast growth factor -1/2, angiopoietin-2, epidermal growth factor (EGF), HB-EGF, bone morphogenetic protein-9, endoglin, endothelin-1, granulocyte colony stimulating factor, hepatocyte growth factor, interleukin-8, follistatin, placenta growth factor and leptin. The location of angiogenesis factors was monitored by immunofluorescence labeling and confocal laser scanning microscope 3D reconstruction. RESULTS: Endometrial stromal cells and glandular epithelial cells were isolated and primary cultured for establishing a 3D co-culture system. The levels of VEGF-A/C/D in Danzhi decoction group and aspirin group were significantly lower than those in mock group (P0.05). Furthermore, the alterative location of VEGF-A/C/D was observed in the cytoplasm of endometrial glandular epithelial cells. CONCLUSIONS: Danzhi decoction may inhibit the expression of VEGF in the blood stasis microenvironment of SPID by targeting the cytoplasm of endometrial glandular epithelial cell.
