Why humans have a philtrum, the groove above your lip, explained by an evolutionary biologist — from embryonic face-building ...

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human body ...

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 production ...

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, ...

Human embryo models can help researchers study early human development and infertility without relying solely on human ...

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

"Guinea pigs can become a valuable model for understanding how early disturbances in embryonic development can affect health later in life. Since guinea pig development mirrors that of humans better ...
