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, ...

Anatomy education in 2026 is shifting from siloed memorization to integrated systems thinking, where the digestive system serves as the perfect anchor to connect joint mobility, epithelial barriers, ...

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 ...

Normal epithelial cells show the ability to push out precancerous ones present in the epithelium, by means of 'cell competition.' But the exact molecular mechanism of this recognition by normal ...

This is part of a series of stories on the protective role of innate lymphoid cells (ILCs) in the gut and other tissues, focusing on SARS-CoV-2 infection. Part one can be read here. The Milky Way ...

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 ...

Researchers at the School of Medicine at the University of California, Riverside have discovered previously unrecognized ...

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 ...
