Gradients of signalling molecules dictate where specific cell types form in developing tissues, but how these gradients are set up is much debated. A model proposed 40 years ago by Francis Crick may ...

Tissue patterning is an important process during embryo formation, which ensures that groups of cells are arranged in an appropriate manner that allows them to function properly. Tissue patterning is ...

Biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body ...

In a recent study published in Nature Communications, researchers examinea the effects of temporal morphogen gradient during neural induction (NI) on the formation of brain organoids. Study: Temporal ...

A decades-old explanation for how tigers get their stripes has come into question as researchers challenge what’s called the morphogen theory. The research does not nix the theory, but science may now ...

Just a few weeks after conception, stem cells are already orchestrating the future structure of the human brain. A new Yale-led study shows that, early in development, molecular “traffic cops” known ...

Morphogens are signaling molecules that are vital for cell differentiation. These molecules directly influence cell differentiation, inducing specific cellular responses in relation to their ...

Cells producing noise in the Wnt morphogen gradient are sensed by neighboring cells through E-cadherin and then eliminated through the Smad-ROS (reactive oxygen species) axis. Disclaimer: AAAS and ...
