Fetal Programming of Newborn TL
… the origins of these diseases. Telomere length (TL) in early life is a promising biomarker of long-term disease risk and longevity, and there is growing evidence that TL reflects experiences during fetal development. However, the link between maternal mental health during pregnancy and offspring …
