Newborn mice neurons can snap both DNA strands to migrate, then repair the breaks within a day. The process may be a normal ...

During tissue regeneration, cells are recruited from surrounding tissue to the defect site. However, when the defect site is large and morphologically complex, cell recruitment often fails to match ...

Newborn nerve cells must squeeze through crowded, narrow spaces—through dense tissue, past other cells, and between fibers—to reach the areas where they form neural circuits in the brain cortex. In a ...

Lysosomes are membrane-bound organelles that play a crucial role in cellular homeostasis by maintaining nutrient recycling, degrading cellular waste, and regulating various cellular processes. 1 They ...

Following an injury, such as a traumatic crush injury, the peripheral nervous system is itself often able to effectively regenerate. This regeneration capacity is mainly attributable to the Schwann ...

Migrating newborn neurons suffer routine double-strand DNA breaks from physical stress during brain development.

Amyotrophic lateral sclerosis (ALS) is a relatively rare but very serious disease of the nervous system. A cure is not yet possible. ALS slowly destroys the motor neurons in the brain and spinal cord ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...

As muscles age, their cells lose the ability to regenerate and heal after injury. Cornell Engineering researchers have created the most comprehensive portrait to date of how that change, in mice, ...

Capitalizing on the flexibility of tiny cells inside the body's smallest blood vessels may be a powerful spinal cord repair strategy, new research suggests. Capitalizing on the flexibility of tiny ...
