WEST LAFAYETTE, Ind. - A Purdue University study shows that Notch signaling, a key biological pathway tied to development and cell communication, also plays an important role in the onset of obesity ...

Combined experimental and theoretical tools that include biochemical and molecular biology approaches, genome, transcriptome, and proteome analyses, and comparative methods, have advanced our ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing how a specialized signaling center shapes both cell identity and tissue ...

A new type of brain cell, called a glutamatergic astrocyte, has been discovered. It could explain how a variety of neurodegenerative conditions, such as Parkinson’s, develop. Brain cells can largely ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...
