Maternal hyperglycemia, induced by gestational diabetes mellitus (GDM), has detrimental effects on fetal vascular development, ultimately increasing the risk of cardiovascular diseases in offspring. The potential underlying mechanisms through which these complications occur are due to functional impairment and epigenetic changes in fetal endothelial progenitor cells (EPCs), which remain less defined. We confirm that intrauterine hyperglycemia leads to the impaired angiogenic function of fetal EPCs, as observed through functional assays of outgrowth endothelial cells (OECs) derived from fetal EPCs of GDM pregnancies (GDM-EPCs). Notably, PCDH10 expression is increased in OECs derived from GDM-EPCs, which is associated with the inhibition of angiogenic function in fetal EPCs. Additionally, increased PCDH10 expression is correlated with the hypomethylation of the PCDH10 promoter. Our findings demonstrate that in utero exposure to GDM can induce angiogenic dysfunction in fetal EPCs through altered gene expression and epigenetic changes, consequently increasing the susceptibility to cardiovascular diseases in the offspring of GDM mothers.

Previous studies demonstrated an association between cervical strain and risk of spontaneous preterm delivery (sPTD). The present study aimed to assess the efficacy of elastography in predicting sPTD at <32 weeks of gestation in women with singleton pregnancies receiving progesterone for short cervix (≤2.5 cm) diagnosed between 16 and 28 weeks of gestation Among 115 participants eligible for analysis, nine had sPTD at <32 weeks. Preprogesterone (PP0) mean internal os strain (IOS), elasticity contrast index (ECI), hardness ratio (HR), one-week postprogesterone (PP1) IOS, mean external os strain (EOS), ECI, and HR were significantly different between groups. Higher PP0 IOS, PP1 IOS, and PP1 EOS were associated with a 2.92, 4.39 and 3.65-fold increase in the risk of sPTD at <32 weeks, respectively (adjusted for cervical length (CL) at diagnosis; p = 0.04, 0.012 and 0.026, respectively). A combination of CL at diagnosis, PP0 IOS and PP1 EOS showed a significantly higher area under the receiver operating characteristic curve (0.858) than that of CL alone (p = 0.041). In women with singleton pregnancies receiving progesterone for short cervix, cervical elastography performed before and one week after progesterone treatment may be useful in predicting sPTD at <32 weeks of gestation.

Yun Ji Jung, M.D., Ph.D. is a Clinical Assistant Professor in the Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, at the Institute of Women’s Medical Life Science, Yonsei University College of Medicine. She received her BS in Medicine (2010) and PhD in OBGYN (2021) from Yonsei University.
Dr. Jung has actively contributed to the field of maternal–fetal medicine through numerous peer-reviewed publications, academic presentations, lectures, and educational courses. She holds memberships for key professional societies, including the Korean Society of Obstetrics and Gynecology, the Korean Society of Maternal-Fetal Medicine, the Korean Society of Ultrasound in Obstetrics and Gynecology, and the International Society of Ultrasound in Obstetrics and Gynecology. She has also served on multiple committees within these societies, reflecting her leadership and commitment to advancing clinical practice and education.
Her research interests encompass pre-eclampsia, fetal growth restriction, in utero fetal programming, preterm birth, and artificial intelligence-based ultrasound automation. Her scholarly excellence has been recognized through several prestigious awards, including the S.S. Ratnam - Young Gynaecologist Award from AOFOG and multiple best presentation awards at national academic congresses.
