Vascular endothelial growth factor (VEGF) expression in histological endometritis in the bitch: An immunohistochemical study.

This work aimed to study the immunolocalization of vascular endothelial growth factor (VEGF) and its FLT-1 receptor (VEGFR1) in systemically healthy bitches with and without endometritis (END). Thirty-one uterine samples from mixed-breed, systemically healthy diestrous bitches, were included in the study. The bitches were divided into three groups after histological evaluation (normal endometrium [n = 8]; acute-END [n = 8]; subacute-END [n = 5]; chronic-END [n = 10]). The immunohistochemical localization of VEGF and VEGFR1 were detected following standard procedures. Data were analysed using SPSS 26.0. Immunoreactions were detected in cells from the luminal epithelium (LE), epithelium of the superficial glands (ESG) and epithelium of the deep glands (EDG), and some cells localized in the stroma. Immunostaining of VEGF in acute-END was higher than chronic-END (p < .05) and was higher in LE than EDG (p .017). Marked-area was higher in END than normal endometrium in VEGFR-1 (p < .004). The current results provide new information on the END in systemically healthy females. Data reported here indicate that VEGF could be involucrated in the pathogenesis of END. Future studies could provide more information, support our results and elucidate the role of VEGF in the pathogenesis of END. © 2022 Wiley-VCH GmbH.
