A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

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 ...

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 ...

In April, researchers in China reported that they had initiated pregnancies in monkeys through a procedure seemingly much like in vitro fertilization (IVF), in which embryos created in a dish were ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

An international team of scientists has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape.

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