The process of a single-celled zygote developing into a complex multicellular organism is precisely regulated at spatial and temporal levels in vivo. However, understanding the mechanisms underlying ...

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 ...

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 ...

In primates, abnormalities during gastrulation and early organogenesis lead to a high incidence of early abortion and developmental defects at birth 8. Thus, elucidating the cellular and molecular ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

The researchers identified several conserved pathways, including the Hippo, MEK-ERK, and JAK-STAT systems, which control the differentiation of embryonic cells in both guinea pigs and humans.

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating bird embryonic stem cells (ESCs) in the lab. Using a growing medium of egg ...

Researchers at Kumamoto University have achieved a notable advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture system ...

In what he refers to as a "small step," an MU researcher has coaxed stem cells harvested from pig blood into becoming bone, blood vessel and neural cells. Elmer Price, a professor of biomedical ...

Humans have around 30 trillion cells in our adult bodies. Amazingly, each of these cells came from a handful of about 100 stem cells in the earliest days of development. The ability of these embryonic ...

Among the body's most crucial protective features are the brain barrier systems, including the blood-brain and blood-cerebrospinal fluid (CSF) barriers. These barriers are made of highly specialized ...
