evaluation of autogenous fibrinogen extracted from horse blood in fibrin glue and it's effects on horse's fibroblast and keratinocyte cells were preformed. fibrinogen has been obtained by glycine precipitation technique from horse's blood. fibroblast cells were separated by explant culture method from neck skin and keratinocytes were separated by enzyme digestion from lib samples...

BACKGROUND Primary keratinocytes derived from epidermis, oral mucosa, and urothelium are used in construction of cell based wound healing devices and in regenerative medicine. This study presents in vitro technology that rapidly expands keratinocytes in culture by growing monolayers under large volumes of serum-free, essential fatty acid free, low calcium medium that is replaced every 24 hrs. ...

Introduction: Osteoarthritis (OA) represents an increasing health issue worldwide. Regenerative medicine (RM) has raised the hope for introducing revolutionary therapies in clinical practice. Detection of autologus cell sources can improve accessibility to RM strategies. Objectives: to assess the presence and biological potential of mesehchymal stem cells in three tissues (subchondral bone, syn...

The epidermis basal layer is composed of two keratinocyte populations: Keratinocyte Stem cells (KSC) and Transitory Amplifying (TA) cells that arise from KSC division. Unfortunately, no specific marker exists to differ between KSC and TA cells. Here, we aimed at comparing two different methods that pretended to isolate these two populations: (i) the rapid adhesion method on coated substrate and...

background: extensive full-thickness burns require replacement of both epidermis and dermis. in designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. methods: in the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...
