Content overview: “How Cell Division Reshapes Tissues: New Study Reveals Biomechanical Forces at Work”. Scientists have long known that cell division is essential for growth and renewal, but a new study reveals it does more than just create new cells—it actively reshapes tissues. Researchers from the University of California, San Diego, led by biophysicist Otger Campàs, found that when a cell divides in a crowded tissue, it generates forces that reorganize neighboring cells, effectively remodeling the tissue's structure. This discovery, published in Nature Physics, solves a long-standing puzzle: how do tightly packed cells make room for daughter cells without disrupting tissue integrity?
The team studied epithelial tissues—the sheets of cells that line organs and body cavities—using advanced imaging and mechanical measurements. They discovered that dividing cells push outward, causing neighboring cells to rearrange and flow around the division site.
