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, ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

UCSF’s Program in Craniofacial Biology (PCB) brings together researchers to study the cellular and molecular mechanisms underlying craniofacial development and birth defects, such as cleft lip and ...

The NCI grant is allowing Xu’s team to continue dissecting the interactions among Lfng, Notch3, and other key signaling pathways involved in PDAC initiation and progression. The goal is to translate ...

A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...
