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 distinct signaling pathway called TNF- drives the transformation of epithelial cells into aggressive tumor cells. During cancer progression, cells activate their own TNF- program and become invasive ...

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...

Dr. Umapathy Sundaram, known as Uma to colleagues, directs research efforts that translate molecular discoveries into ...

The intestinal epithelium undergoes rapid renewal every 3–5 days, a process driven by intestinal stem cells (ISCs) located at the base of crypts. While ISCs play an essential role in epithelial ...

Researchers identify altered expression of genes that worsens periodontitis among smokers, and a new target molecule ...

Side section of the skin with epidermal stem cells (green) with one particular clone in red. Cell nuclei are stained in blue, the white dashed lines indicate hair follicles. How does a normal cell in ...
