Definitions
- the invention relates to a process for the production of bioprostheses from allogeneic or xenogeneic material, in particular heart valves, in which the collagen matrix of the transplant remaining as a result of detergent treatment for lysing and killing the cells is populated with the body's own cells of the transplant recipient.
- the invention is equally applicable to other material such as blood vessels, bone cartilage, ligaments and the like. , applicable.
- a method for the production of biological prostheses, in particular for cardiac and vascular surgery, has already been proposed, in which a foreign material suitable as a bioprosthesis, for example a porcine aortic valve, is first treated with deoxycholic acid for decellularization, which is then treated with physiological Saline is washed out again.
- the collagen matrix obtained in this way is coated with a natural adhesive and then coated with the body's own cells.
- Both the decellularization and the subsequent coating with the body's own cells takes place under dynamic conditions, in particular in a liquid flow adapted to the natural flow conditions in the organ or vessel in question, in order to condition the decellularized foreign material, that is, the prerequisites for an all areas of the To create foreign cell uniform cell growth and to ensure a long shelf life of the bioprosthesis in the body.
- Pig whose aortic valve has proven to be well suited for use in bioprostheses, integrates endogenous replication-capable retroviruses into the genome, which can multiply in human cells.
- the subsequent dynamic conditioning does not meet all the requirements for rapid and safe growth and even colonization of the graft with the body's own cells of the recipient of the bioprosthesis, since the surface of the graft after the detergent treatment can be changed in a way that can hinder the uniform and reproducible growth and further growth of cells on the graft.
- the invention is therefore based on the object of specifying a method for producing bioprostheses from allogeneic or xenogeneic material which ensures reproducible, uniform colonization with the body's own cells and provides a graft free from pathogens with a long service life.
- the basic idea of the invention consists in conditioning the collagen matrix remaining after the killing and removal of the foreign cells with a detergent medium in a solution of cyclic ß-hydroxy fatty acid and ß-amino fatty acid-containing peptides (lipopeptides), in particular in a solution of surfactin as a cyclic heptapeptide, in which a ß-hydroxy-
- Fatty acid is integrated and the ring is closed by the lactone bond of the ⁇ -hydroxyl group with the carboxyl group of the terminal leucine building block. It was surprisingly found that, in particular, surfactin, which has the structure shown below
- the surface of the graft is influenced by the physical-chemical properties (ie surface, interface and membrane active properties) of the cyclic lipopeptide in a way that ensures a uniform colonization of all surface areas of the matrix with the body's own cells of the transplant recipient ,
- a major advantage of the use according to the invention of the thermally stable and therefore thermally sterilizable cyclic lipopeptides, in particular suractin, lies in their antiviral and antimicrobial activities, so that the elimination of any pathogens already brought about by detergent treatment is additionally ensured.
- the lipopeptide treatment ensures that even the smallest residues on the surface of any remaining detergents are removed. Because of all the advantageous effects of conditioning with a cyclic lipopeptide, a rapid and uniform colonization of the tissue matrix is finally ensured, which consequently has a smooth surface and therefore does not tend to calcify and also has a higher elasticity than the known grafts. As a result of the method according to the invention and its effects, grafts with a long lifespan can be provided.
- a fat-free and tailored porcine aortic valve is stored in a 1-2% deoxycholic acid (or detergent with a similar effect) at 37 ° C for up to 24 hours.
- the deoxycholic acid dissolves the adhesive connection of the cells with the tissue matrix and at the same time has a killing effect on the cells.
- phosphate buffer solution and, if necessary, an intermediate treatment with alcohol, the cells or
- the aortic valve is in a pulsating media flow during the flushing process.
- the porcine aortic valve treated in this way is then placed in a buffered surfactin solution at 37 ° C. for three hours and then washed 5 times with 10 minutes with physiological saline solution.
- the surfactin which has a very low toxicity (200 mg / kg) and, under suitable conditions and has no effect on human or animal cells, is able to lyse microorganisms, such as mycoplasma and enveloped viruses, is an excellent one after the detergent treatment Conditioner for the decellularized porcine aortic valve.
- the surfactin not only has an antiviral and antibacterial effect, but also displaces residues of the deoxycholic acid that may remain on the collagen matrix of the aortic valve and is modified as a result of an interaction with the collagen due to its membrane-active, surface-active properties the surface of the tissue matrix in such a way that uniform colonization with cells and rapid and uniform cell growth is ensured in all surface parts of the cellular aortic valve.
- Additional conditioning of the tissue matrix after the treatment in surfactin can additionally be carried out in such a way that cell colonization and cell growth take place in a pulsating media stream.
