Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

Every year, around 15 million babies worldwide are born before 37 weeks of gestation. Being born preterm can disrupt development, and earlier births increase the risk of life-changing health outcomes.

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what you look like: the pigments of your eyes, of your skin, and the bone ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...

Here’s what a pregnancy looks like inside a microfluidic chip. At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining of the ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Catholics on social media have been sounding the alarm on a chilling new trend: turning embryos into jewelry. Embryos — frozen children — who are no longer wanted by a family are literally killed to ...

In 2018, Chinese scientist He Jiankui shocked the world when he revealed that he had created the first gene-edited babies. Using Crispr, he tweaked the genes of three human embryos in an attempt to ...

During in vitro fertilisation (IVF), embryos undergo genetic testing before they are transferred to the uterus – but researchers have found that a widely used test cannot detect genetic abnormalities ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

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 - ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...
