چکیده

BACKGROUND When treating extensively burned patients using cultured epidermal sheets, the main problem is the time required for its production. Conventional keratinocyte isolation is usually done using Trypsin. We used a modification of the conventional isolation method in order to improve this process and increase the number of colonies from the isolated epidermal cell population. PURPOSE To compare the action of trypsin and thermolysin in the keratinocyte isolation using newborn foreskin. METHODS This method used thermolysin as it selectively digests the dermo-epidermal junction. After dermis separation, the epidermis was digested by trypsin in order to obtain a cell suspension. RESULTS Compared to the conventional procedure, these experiments demonstrated that in the thermolysin group, the epidermis was easily detached from the dermis, there was no fibroblast contamination and there were a larger number of keratinocyte colonies which had a significant statistical difference. CONCLUSION The number of colonies in the thermolysin group was significantly greater than in the trypsin group.

Isolation and Cultivation of Adult Human Keratinocyte Stem Cells for Regeneration of Epidermal Sheets

Background: Keratinocyte stem cell is one of the adult stem cells that inhabits the skin and contributes to skin function and renewal. Adult stem cells are best defined by their capacity to self-renew, and to maintain tissue function for a long period of time. These findings indicate the importance of these cells for clinical applications including regenerative medicine, tissue engineering and ...

In vitro Co-Culture of Human Skin Keratinocytes and Fibroblasts on a Biocompatible and Biodegradable Scaffold

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...

Investigation the effect of copper nanoparticles on the toxicity and migration of keratinocyte cells

Background: Re-epithelialization has an important role in skin wound healing. Delays in re-epithelialization are more likely to create the chronic wound. Impaired wound healing leads to a large burden of morbidity and mortality. Current treatments based on the use of autografts, allografts and xenografts, suffer from limitations such as, quantity of donor skin available, donor-site infection, p...
