Researchers from the University of Granada have grown artificial skin from the adult stem cells of an umbilical cord. The paper inl Stem Cells Translational Medicine shows the ability of Wharton jelly mesenschymal stem cells to turn to oral-mucosa or skin-regeneration epithelia.
To grow the artificial skin the researchers also used a biomaterial made of fibrin and agarose, designed and developed by the University of Granada research team. The work has been carried out in the laboratories of the Faculty of Medicine, alongside the Experimental Unit of the Granada "Virgen de las Nieves" University Hospital Complex.
Prior studies from this same research team, which received recognition in the World Congress on Tissue Engineering, held a few months ago in Seoul (S. Korea), already pointed to the possibility that Wharton stem cells could be turned into epithelia cells. This current work is the confirmation of those initial studies and its application to two regeneration structures: skin and oral mucosa, increasingly needed in injuries in these parts of the body.
One of the problems major-burn victims currently have is that, in order to apply the current techniques of artificial skin, a number of weeks are needed. That is because the skin needs to be grown from parts of the patient's healthy sin.
"Creating this new type of skin using stem cells, which can be stored in tissue banks, means that it can be used instantly when injuries are caused, and which would bring the application of artificial skin forward many weeks", as explained by Antonio Campos, Professor of Histology at the University of Granada and one of the authors of this study.
