A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

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 ...

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

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

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 - ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as "junk" plays a crucial role in the earliest moments of life. The research, ...
