Problem:Question: Does vEGFR-1 blockade disrupt peri-implantation decidual angiogenesis and macrophage recruitment?
Answer: We found that VEGFR-1 functions in both decidual angiogenesis and macrophage recruitment to the implantation site during pregnancy. VEGFR-1 is expressed by endothelial cells, however blocking VEGFR-1 function in endothelial cells results in reduced macrophage recruitment to the uterus. VEGFR-1 blockade did not compromise the establishment and/or maintenance of pregnancy.
Solution:
yes
