Precision IVF tracks how mouse embryos switch on their genome

Researchers at EMBL Rome have developed a precision IVF protocol for mice to study embryonic genome activation (EGA) in high resolution. The study reveals that embryos exhibit significant variations in gene expression timing shortly after fertilization.
Why it matters
Understanding the fundamental mechanisms of early embryonic development provides essential insights into reproductive biology and potential advancements in fertility treatments.

Shortly after fertilization, the newly formed embryo faces a remarkable challenge: it must switch from relying on molecules supplied by the mother to using its own genome. This process, known as embryonic genome activation (EGA), is one of the earliest and most important steps in development.
