In this experimental animal study, we assessed the recipient animals using various biomarkers, including rate of angiogenesis (serum levels of VEGF‐A and vessels count), serum levels of CA‐125, inflammatory biomarkers (TNF‐α in peritoneal fluid and IL‐37 in blood serum), oxidative stress biomarkers (NO and MDA in peritoneal fluid) and histological assessments to ensure that the new model accurately imitated human endometriosis. Here, VEGFA is linked to endometriosis.
