A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

Researchers 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, each cell has the ...

Researchers 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 weeks after fertilization. This is ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Infertility is a major healthcare concern. Understanding the molecular regulators governing fertilization, early embryonic ...
