A newly discovered cell that matures into two specialist cell types – an immune cell responsible for tissue repair and a cell that forms blood vessels – significantly boosts wound healing, according ...

The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens. It's a dangerous world out there. From bacteria and ...

Wound repair is an essential component of life. Without it any minor cuts or scrapes could be extremely damaging or even lethal. Paper cuts are bad enough already without having to consider them ...

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, ...
