Lin28: Time for Tissue Repair
Embryos and juveniles in many organisms repair tissue injuries better than adults. In this issue, Shyh-Chang et al. find that postnatal activation of Lin28a, a gene typically active in embryonic development, promotes better than normal tissue repair in mice, including following ear and digit injuries.
متن کاملLin28 Enhances Tissue Repair by Reprogramming Cellular Metabolism
Regeneration capacity declines with age, but why juvenile organisms show enhanced tissue repair remains unexplained. Lin28a, a highly conserved RNA-binding protein expressed during embryogenesis, plays roles in development, pluripotency, and metabolism. To determine whether Lin28a might influence tissue repair in adults, we engineered the reactivation of Lin28a expression in several models of t...
متن کاملElectrospun Nanofibers and their Application in Tissue Repair and Engineering
Introduction: Tissue engineering is the repair and replacement of damaged tissues and requires a combination of cells, growth factor and porous scaffolds. Scaffolds, as one of the main components in tissue engineering, are used as a template for tissue regeneration and induction and guidance of growth of the new and biologically active tissues. An ideal scaffold in tissue engineering, imitating...
متن کاملDental Tissue Repair: Novel Models for Tissue Regeneration Strategies
Studies have shown that dentin matrices contain reservoirs of bioactive molecules capable of directing tissue repair. Elucidating the release mechanisms of such endogenous growth factors will enhance our understanding of dentinpulp regeneration and support the development of novel treatment modalities to enhance dentin repair following trauma and disease. Current clinical practice using new mat...
متن کاملRepair of Minor Tissue Defect in Hand by Transfer of Free Tissue Flap from the Toe
Background: To introduce our experience of using the free neurovascular flap from great and second toe. Methods: Thirteen patients (fifteen fingers) sought surgical treatment for soft tissue defects of the hand at our medical institutin between March 2006 and September 2009. In two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. I...
