By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate, move and exert mechanical forces on each other as ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

Together with his student Hilde Mangold, the biologist Hans Spemann discovered the so-called »organiser« during embryonic development in 1924. In ...

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 ...

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 ...

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 ...
