Modeling weighted transfer ratios enable statistical analysis of maternal–infant transfer at a more general level and can indicate whether any transfer is persistent, transient, or originates from alternate sources.

Maternal spindle transfer is a feasible approach to enhance embryonic developmental of compromised oocytes, which can represent a new strategy for patients with forms of infertility refractory to current treatments.

The inclusion of the patient couple's clinical features along with blastocyst images increases live birth prediction accuracy.

In vitro analyses reveal how vertical DNA transmission from the mother to the pre-implantation embryo via endometrial extracellular vesicles can impact embryo bioenergetics.

Maternal obesity alters the fetal cardiac and serum lipidome, promoting early fetal cardiac metabolic maturation, with evidence that the female heart lipidome is more responsive to an in utero obesogenic environment.

An ancestral enzyme tailors allocation of essential lipid resources to the progeny and connects maternal and embryonic sterol metabolism for reproductive success.

Growth-delayed offspring generated from eggs that lacked normal epigenetic programming exhibited a remarkable capacity to undergo late gestational fetal growth recovery, despite inefficient placental function.

Epigenetic reprogramming by LSD1/KDM1A acts at fertilization in mice to enable embryogenesis and prevent behavioural abnormalities.

Active uptake and metabolism of maternal vitamin D by the placenta determine fetal exposure to vitamin D and how vitamin D regulates the placental transcriptome, which is also determined by its underlying epigenetic landscape, and proteome.

In wild bonobos, sibling birth induced a sudden increase in urinary cortisol levels in the older offspring, a physiological response that occurred in all subjects and was independent of their age.
