British researchers from the University of Surrey have developed a technology that will produce three-dimensional scaffolds for growing skin grafts, which can then be implanted in patients with extensive wounds. The article was published in the scientific journal magazine Nanomaterials.
Scientists used the method of electrospinning or electrospinning, in which fibers are formed from a liquid polymer under the influence of an electric field. This method made it possible to create structures in which skin cells were twice as viable compared to those cultured in two-dimensional films.
The new scaffolds are made from a solution of gelatin and polycaprolactone, a biodegradable plastic that is compatible with human tissue.
Experts noted that the technology they created was simple, cheap and scalable. Adjusting the magnetic field parameters also allows you to create muscle fiber structures. In the future, the method could enable bone and cartilage growth, which would speed up people’s recovery from illness and injury, the researchers say.
Previous scientists printed Functional ventricle of the heart on a 3D printer.
