Abstract
La invención se refiere a un apósito aplicable sobre una herida, que comprende una capa de soporte dotada de una capa no adherente a las células sobre su cara orientada hacia la herida. Dicha capa no adherente está soldada a una capa biodegradable de anclaje a células que se ancla a células mamalianas. Durante su utilización, la capa biodegradable se descompone y libera las células sobre el sitio de la herida, impidiendo la capa no adherente que dichas células se fijen posteriormente al apósito. Este apósito puede entonces pasar de un estado de conexión a las células a un estado en el que se impide esta conexión a las células . La invención se refiere además a sistemas, a métodos de tratamiento y a procedimientos de fabricación de este apósito.
