A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Chinese researchers sent artificial human embryo models into space to study how microgravity may affect early human development.

Researchers from the Kind Group have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

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 ...

Sperm may carry molecular messages shaped by a father's life experiences, potentially influencing embryo development beyond ...

Researchers from the University of Adelaide have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Professor Rebecca Robker, ...

New York researchers took healthy human embryos and successfully modified their genetic code by focusing on a single letter.

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...
