Laminin 5 deposition regulates keratinocyte polarization and persistent migration.
Repair of wounded epidermis requires both keratinocyte migration and deposition of laminin 5 over exposed dermal collagen. To understand the coupling between leading cell migration and laminin 5 deposition, we developed a novel migration assay using time-lapse microscopy. We demonstrate that in migrating, human keratinocytes the deposition of laminin 5 promoted 'processive migration', character...
متن کاملHIF1 transcription factor regulates laminin-332 expression and keratinocyte migration.
Epidermal wound repair is a complex process involving the fine orchestrated regulation of crucial cell functions, such as proliferation, adhesion and migration. Using an in vitro model that recapitulates central aspects of epidermal wound healing, we demonstrate that the transcription factor HIF1 is strongly stimulated in keratinocyte cultures submitted to mechanical injury. Signals generated b...
متن کاملHuman lactoferrin stimulates skin keratinocyte function and wound re-epithelialization.
BACKGROUND Human lactoferrin (hLF), a member of the transferrin family, is known for its antimicrobial and anti-inflammatory effects. Recent studies on various nonskin cell lines indicate that hLF may have a stimulatory effect on cell proliferation. OBJECTIVES To study the potential role of hLF in wound re-epithelialization. MATERIALS AND METHODS The effects of hLF on cell growth, migration...
متن کاملA wound-induced keratin inhibits Src activity during keratinocyte migration and tissue repair
Injury to the epidermis triggers an elaborate homeostatic response resulting in tissue repair and recovery of the vital barrier function. The type II keratins 6a and 6b (K6a and K6b) are among the genes induced early on in wound-proximal keratinocytes and maintained during reepithelialization. Paradoxically, genetic ablation of K6a and K6b results in enhanced keratinocyte migration. In this pap...
متن کاملBone morphogenetic protein signalling suppresses wound-induced skin repair by inhibiting keratinocyte proliferation and migration
Bone morphogenetic protein (BMP) signaling plays a key role in the control of skin development and postnatal remodeling by regulating keratinocyte proliferation, differentiation, and apoptosis. To study the role of BMPs in wound-induced epidermal repair, we used transgenic mice overexpressing the BMP downstream component Smad1 under the control of a K14 promoter as an in vivo model, as well as ...
