Stem cells are a hot topic for creating medical treatments. However, scientists still do not fully understand how they choose to divide or differentiate to renew organs. Researchers have now found a ...

Researchers have discovered a new way that epithelial cells, which form layers in organs like the skin and stomach, attach to one another, and how they perceive growth signals at these attachments, ...

A section through the retinal pigment epithelium layer from an infected ACE2-expressing mouse: upper image, bright-field plus SARSCoV-2 N-protein (green) and complement component C3b ...

The human stomach operates in an environment with a lumen pH between 1 and 3, yet its own tissues remain intact. This resilience comes from a multilayered defense system: a mucus-bicarbonate barrier ...

In a recent Biomaterials study, researchers evaluate the feasibility of tonsil epithelial cell-derived organoids as an ex vivo model for studying severe acute respiratory syndrome coronavirus 2 ...

The small airways serve as a primary line of defense against inhaled particles and facilitate gas exchange by directing air to the alveoli. These small airways are critical in the pathophysiology of ...

Your gut is a wondrous place. A special layer of cells that coats the insides of your small and large intestines takes in nutrients and water from what you ate while keeping anything bad out of your ...
