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

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 ...

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

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 ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

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 ...

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 ...
