A mouse digit does not usually grow back once it is amputated above the tip. It seals the wound, lays down scar tissue, and ...

For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are ...

Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the body's organs—can respond to death and destruction with a burst of ...

There was a lack of effective, cell-free biomaterials for bladder tissue regeneration that could reliably restore function without the complexities and risks of cell-seeded scaffolds. The breakthrough ...

MXene nanoparticle scaffolds have been shown to stimulate muscle growth, making them a promising option to treat muscle loss and damage. Now, researchers explain the molecular mechanisms behind their ...

The scientists, co-led by Wei Wang, PhD, and colleagues, performed a side-by-side genetic comparison between mammal species—including rabbits—that can regenerate ear tissue and those—including ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Newborns with heart complications can rely on their newly developed immune systems to regenerate cardiac tissues, but this isn’t the case in adults. After a heart attack, most adults struggle to ...

In contrast to mammals, adult zebrafish achieve complete heart regeneration via proliferation of cardiomyocytes. Surprisingly, we found that regenerating cardiomyocytes experience DNA replication ...
