Thermolysin in human cultured keratinocyte isolation.

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 ...

Isolation and in vitro cultivation of human skin Keratinocytes and preparation of epidermal sheet

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...

کشت کراتینوسایت های موش صحرایی در محیط کشت بدون سرم به روش کاشت اپیدرم

Background and purpose: To establish a simple method for preparation of pure epidermal cell in serum-free medium, without co culturing with lethally irradiated 3T3 cells. Materials and methods: Â piece of skin biopsy was taken from a rat. Âfter trypsinazation to separate epidermal layer, the epidermis was cut into explants 1×1 mm and were laid at 50 mL on tissue cultured flasks. Then, the ex...
