Fuente: WIPO "tomato" A new method to obtain a matrix loaded with blood cells is herein disclosed. The method comprises the steps of: (a) providing: a liquid phase containing blood cells; a solid matrix connecting said liquid phase with a positive electrode; a solid matrix connecting liquid phase with a negative electrode; and (b) applying an electric field between positive and negative electrodes, resulting in a movement of blood cells towards one of the electrodes and in cell-loading of the corresponding matrix. The method results in efficient and homogeneous incorporation of the blood cells into the solid matrix by electrical field application. The matrix obtained by this method is suitable for medical use, in particular for wound healing and tissue regeneration purposes.
