Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it under a microscope. A human blastoid is a stem-cell-made copy of an early ...

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

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

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...
