In epithelial tissues, juxtaposition of cells of different phenotypes can trigger cell competition, a process whereby one type of cell drives death and extrusion of another. During growth and ...

Cell walls are a crucial structure of plant life, protecting cells from damage, giving plants shape, and containing energy-rich nutrients. And yet the process of how the walls begin to form remains ...

Dead cells after the self-destruction and fragmentation process. The large green areas are the “eat me” signals which alert immune cells to kick-start clean-up and recycling process, while the small ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

The progression of malignant tumors leads to the development of secondary tumors in various organs, including bones, the brain, liver, and lungs. This metastatic process severely impacts the prognosis ...

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

Scientists have developed a powerful new technique that allows them to observe how individual cells manufacture proteins during aging, offering an unprecedented glimpse into the hidden molecular ...

Cutaneous squamous-cell carcinoma (SCC) is primarily caused by oncogenesis mediated by ultraviolet radiation, and β-human papillomavirus (β-HPV) is believed to be a mere facilitator that is ...

Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...
