In the earliest stages of life, mammalian embryos start as a disorganized cluster of cells. As development progresses, these cells become organized into well-defined shapes and structures. This ...

Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

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

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Researchers led by developmental biologist Kathy Niakan at the University of Cambridge have used base editing in human embryos to learn more about human embryonic development. By deactivating a gene ...

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, ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

A study published today in the journal Developmental Cell uncovers new insights into how the heart forms during the earliest stages of embryonic development. The research, led by scientists at the ...

"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 ...
