Генерация трехмерной всю толщину кожи Эквивалент техники и автоматизированных Ранение

Overview

This protocol outlines the construction of a three-dimensional full thickness skin equivalent that mimics natural skin. It utilizes an automated wounding device to create precise and reproducible wounds while maintaining sterility.

Key Study Components

Area of Science

• Neuroscience
• Biology
• Tissue Engineering

Background

• Full thickness skin equivalents are essential for studying skin biology.
• Automated wounding devices enhance reproducibility in experimental setups.

Purpose of Study

• To create a model that closely resembles natural skin.
• To generate standardized wounds for research purposes.
• To assess the histological structure of the skin equivalent post-wounding.

Methods Used

• Embedding primary human dermal fibroblasts in collagen one hydrogel.
• Seating primary human epidermal keratinocytes on a fibronectin coated hydrogel.
• Culturing the model under submerged conditions and then under an air-liquid interface.
• Using immunohistochemical staining and microscopy for assessment.

Main Results

• A three-dimensional full thickness skin equivalent was successfully formed.
• Standardized wounds were generated in a sterile environment.
• Histological analysis provided insights into the structure of the wounded skin equivalent.
• The automated wounding device proved effective for reproducibility.

Conclusions

• The study successfully developed a model for skin research.
• Automated wounding enhances experimental consistency.
• This model can be used for further studies in skin biology and healing.
