Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

This important study advances a new computational approach to measure and visualize gene expression specificity across different tissues and cell types. The framework is potentially helpful for ...

During pregnancy, the placenta must dig into the uterine wall deeply enough to tap into the mother’s blood supply and nourish ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

Knowing the location of a gene within intact tissue or a single cell allows scientists to unlock unknown cellular functions. This information is often lost in most genetic sequencing techniques, but ...

Cedars-Sinai Health Sciences University investigators have for the first time created human intestinal organoids that include ...

New research reveals the cellular secrets of aging, with cutting-edge single-cell data mapping how neurons, glial cells, and immune systems reshape the aging brain. Study: Brain-wide ...

Type 1 diabetes is an autoimmune condition in which the body attacks its own insulin-producing cells in the pancreas. Some ...
