Ex Vivo Skin Blisters: A New Way to Study Wound Healing!
This study established a novel ex vivo human skin wound model using suction blisters, mimicking the regenerative process of wound healing. The model showed successful re-epithelialization and differentiation of epidermal cells, suggesting its potential for testing wound healing therapies.
Possible Conflicts of Interest
The study was supported by the Medical Scientific Fund of the Mayor of the City of Vienna and Schülke & Mayr GmbH. No other potential conflicts were disclosed.
Identified Weaknesses
Limitations of the ex vivo model
The study acknowledges limitations such as variable wound size due to unequal blister formation. The removal of dermal cells by suction and the lack of new incoming cells from circulation in the ex vivo model might delay re-epithelialization.
Differences in suction parameters between ex vivo and in vivo
The prolonged suction time for ex vivo blistering compared to in vivo, and the need for higher pressure, could be due to the lack of natural skin tension and blood flow in the ex vivo setting. This raises questions about the perfect replication of in vivo conditions.
Further research needed
Addressing the differences between ex vivo and in vivo conditions requires more complex experiments which were not conducted in this study.
Rating Explanation
This study presents a novel and useful ex vivo wound model using suction blisters on human skin. It demonstrates successful re-epithelialization and allows for studying epidermal regeneration. The methodology is sound, and the findings contribute to a better understanding of wound healing processes. The limitations are acknowledged, and the research opens avenues for further investigation. There's no apparent attempt to manipulate the evaluation.
