Regulation of amniotic fluid volume by intramembranous absorption in sheep: role of passive permeability and vascular endothelial growth factor

Research has been conducted on passive intramembranous permeability. The authors have tested the hypothesis that the permeability increases in response to fetal intravascular saline solution infusion, and they suggest that vascular endothelial growth gene expression mediates the intramembranous absorption increase.
