Wound healing and inflammation: embryos reveal the way to perfect repair
Tóm tắt
Tissue repair in embryos is rapid, efficient and perfect and does not leave a scar, an ability that is lost as development proceeds. Wheras adult wound keratinocytes crawl forwards over the exposed substratum to close the gap, a wound in the embryonic epidermis is closed by contraction of a rapidly assembled actin purse string. Blocking assembly of this cable in chick and mouse embryos, by drugs or by inactivation of the small GTPase Rho, severely hinders the re–epithelialization process. Live studies of epithelial repair in GFP–actin–expressing
