DERMIS ARTIFICIAL Y METODO DE OBTECION

Dermis artificial (1) obtenida a partir de plasma con plaquetas (2) y fibroblastos (3) humanos. El plasma con plaquetas (2) se obtiene por fraccionamiento de la sangre total (4) del paciente (8) mediante centrifugación ligera, y los fibroblastos (3) humanos a partir de una biopsia de piel (5).

Beschreibung
Zusammenfassung:	Dermis artificial (1) obtenida a partir de plasma con plaquetas (2) y fibroblastos (3) humanos. El plasma con plaquetas (2) se obtiene por fraccionamiento de la sangre total (4) del paciente (8) mediante centrifugación ligera, y los fibroblastos (3) humanos a partir de una biopsia de piel (5). La gelificación se consigue mediante la adición de calcio. Esta dermis artificial (1) permite un crecimiento rápido de los queratinocitos (6) sembrados en su superficie para constituir una piel artificial (7) que es fácilmente trasplantable. Se consiguen grandes superficies de dermis artificial (1) a partir de una pequeña biopsia de piel (5) y de cantidades mínimas de plasma con plaquetas (2), que al estar enriquecido en citoquinas y factores de crecimiento plaquetario potencia la proliferación de las células sembradas, tanto en su interior como en su superficie. La piel artificial (7) asi obtenida puede servir para el tratamiento de grandes quemados, úlceras cutáneas crónicas... o utilizarse, mediante el empleo de células genéticamente modificadas, como base para terapia génica. SUMMARY Artificial dermis (1) obtained from plasma with platelets (2) and human fibroblasts. The plasma with platelets (2) is obtained from the fractionating of total blood (4) from the patient (8) by light centrifugation, and the human fibroblasts (3) from a skin biopsy (5). Clotting is obtained by adding calcium. This artificial dermis (1) provides for the rapid growth of the keratinocytes (6) seeded on its surface to build an artificial skin (7) which can easily be transplanted. Large areas of artificial dermis (1) are obtained from a small skin biopsy (5) and minimal quantities of plasma with platelets (2), which being enriched with cytokines and platelet growth factors, strengthens the proliferation of the cells seeded, both inside and on the surface. The artificial skin (7) obtained can be used to treat major burn treatments, chronic skin ulcers, etc., or be used, by employing genetically altered cells, as a vehicle for gene therapy.
