Sexual reproduction begins with sperm–oocyte fusion to form a zygote, where chromatin undergoes dramatic reorganization to establish totipotency. Although nucleosomes- the basic units of eukaryotic ...

The team mapped the spatial and temporal patterns of glucose uptake using single-cell-resolution imaging of developing mouse embryos, stem cell models, and embryo-derived tissues. They found that the ...

The quality of oocytes and early embryos is a key determinant of reproductive success. As the primary executors of all cellular functions, proteins orchestrate the molecular events underlying oocyte ...

A stretch of DNA in the mouse genome left by ancient viral infections is crucial for early development in the womb, new research shows. According to the study, published in December in the journal ...

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, ...
