In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

Researchers at Umea University discovered how cells detect and repair damage in lysosomal membranes. Two autophagy protein ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair. Retinoic acid, the active state of Vitamin A, ...

Humans aren't capable of regenerating lost limbs, but our bodies can heal from many wounds. Whenever we scratch or cut our skin, for example, skin stem cells move in to regrow the epidermis and repair ...

Hair follicle stem cells (green) mobilize and expand (white) to help repair the skin’s barrier by differentiating into epidermal lineages (red). When a child falls off her bike and scrapes her knee, ...
