VEGFA and gestational diabetes: The internal environment of placental trophoblast cells of GDM is destroyed, and the cell function is adaptive, which can induce the apoptosis of placental tissue.29 This process is closely linked to the blood supply of placental tissue, and VEGF factor is one of the strongest known angiogenic factors.30 The outcomes of this study revealed that the level of VEGF in the RG was higher relative to the CG, and it was preliminarily speculated that the abnormal expression of serum VEGF might be related to GDM.
