In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Researchers have identified Nr1h2, a critical transcription factor essential for early embryo development. Their findings enhance our understanding of gene regulation during blastoid formation and ...

Oxytocin, a hormone already known for its role in childbirth, milk release, and mother-infant bonding, may have a newfound purpose in mammalian reproduction. In times of maternal stress, the hormone ...

The work appears in Cell. "Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that ...

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to ...

The process of pregnancy is a beautiful miracle and starts with the smallest of seeds, a single cell that develops into a new life within you. These initial days form a loving, protective nest for ...

Successful fertility treatments, including in vitro fertilization (IVF), is often reliant on a clear understanding of developmental stages of human development. Clinicians working with assisted ...

Statements in English by Samuel Ojosnegros Martos, Principal Investigator of the Bioengineering for Reproductive Health Group at the Institute for Bioengineering of Catalonia (IBEC), and leader of the ...
