Every time a tissue grows or renews itself, cells must divide inside an already crowded environment. That creates a fundamental problem that scientists have not fully understood: How does a tightly packed sheet of cells make ...

Changes in our genes affect health risks from heart disease to cancer, but how those genes are turned on and off is just as crucial to health. What's more, almost all genes occur as two copies—one from each parent—that aren't ...

As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into three-dimensional structures ...

In a study of fingertip regeneration, a team led by JAX senior research scientist James Godwin found that some immune cells in mice can attack and kill cells needed to rebuild bone, while a subset of those same immune cells ...

Skeletal muscles grow and regenerate as individual precursor cells—called myoblasts—fuse into long fibers from which mature muscle fibers develop. How they coordinate this process and form functional muscles is not yet fully ...

Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA and then use the host's genetic machinery to reproduce. In doing so, they may have evolved ...

Somatic mutations, the DNA changes that occur as our bodies grow and age, not only hold an important key to cancer but are emerging as the seeds of a wide range of common, noncancerous diseases. The Somatic Mosaicism across ...

Chitin, a chain of repeating sugar molecules, is the main building block of fungal cell walls. When fungi grow or are broken down, fragments of chitin chains of different lengths end up in the soil, and plants detect them ...
