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 ...

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 ...

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 ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

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 ...

Infertility is a major healthcare concern. Understanding the molecular regulators governing fertilization, early embryonic ...
