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 ...

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 ...

Research improves upon a popular experimental model of mammal development and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo. Research from Ph.D ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

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, ...
