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]).
