Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

What happens in the first weeks after a human embryo implants in the uterus has been a black box. Now, biologists have had a chance to study this stage of development in detail for the first time. The ...

Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

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

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

The donation of a miniscule human embryo the size of a poppy seed has given scientists an extremely rare glimpse into an early stage of human development that has long been difficult to study, the ...

The major objection to the use of embryonic stem cells for scientific research seems overcome by the promising development of a way to extract cells and propagate stem cell lines without killing the ...
