They identified the development of two unusual thymic epithelial cell (TEC) states. These age-associated TECs (aaTECs) formed dense clusters in the thymus, lacked thymocytes and displayed ...

Occasional liver cells showed hyaline necrosis ... 3,7,18,19 The single exception may be the distinctive epithelial type of thymoma that has been associated with hyperadrenocorticism.

The blood–thymus barrier regulates exchange of substances between ... The barrier is formed by the continuous blood capillaries in the thymic cortex, reinforced by type 1 epithelial reticular cells ...

Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These ...

Intestinal tuft cells divide to make new cells when immunological cues trigger them. Additionally, in contrast to progenitor- ...

Using miniature human intestines grown in the lab, tuft cells have been found to act as regenerative stem cells in the human ...

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the ...

A group of essential signaling molecules known as the Wnt pathway emerged early in the evolution of multicellular life.

Oct. 3, 2024 — Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report. After transplantation, the macular holes were closed by continuous filling ...
