New York: A method for measuring the limit that human skin can be stretched has been developed by US researchers, which it could help grow new skin for burn victims.
This procedure the skin is stretched, usually, by inflating an air balloon or silicone below the surface. The skin becomes more in regions where it is stretched – during pregnancy, for example -. But it overextended and tissue could break
“Our prediction technique could be employed in this field as a method for predicting the limit that could stretch the skin,” added the German.
The outermost layer of skin, the stratum corneum, regulates water loss and protects the body underlying living tissue of germs and the environment in general. It’s pretty hard, protecting the body from extreme temperatures, rough surfaces, and most of the edges of the paper.
In the study, assuming that the skin is smooth and seamless larger, the researchers observed how the skin hardness varied significantly in relation to their water content. Found dry skin is fragile and easy to break that skin hydrated.
then advanced images were used to further deformation of the skin and stretch, combined with the structure of the skin itself, which correlates with cracks in the skin start.
This may help scientists and doctors predict where future fractures can occur, according to the study.
also found that the cracks in the skin are not straight; Instead, they follow topographical ridges skin, having triangular patterns.
In addition, the team showed that most fractures propagate along cell-cell junctions rather than break the cells themselves. This does not always happen, but suggests that cell junctions are structurally the weakest points of the skin, they said.
The results could help create new medical topical creams, soaps and cosmetics. It can also be used in more extreme cases.
This paper also lays the foundation for a variety of future studies evaluating changes in the composition of the skin, the pH of the environment, or bacterial colonization in the skin resistance of Germany indicated, Article published in the journal Acta Biomaterialia.
