Gene therapy is a potential strategy for treatment of diseases caused by a gene defect. Recent studies are involved particulary in the cure of diseases caused by single gene defect (cystic fibrosis, haemophilia, muscular dystrophy etc.). Our work is part of a project aiming at developing ex vivo non-viral gene delivery systems that could be used for the treatment of ocular and cardiovascular diseases. The gene vectors are biodegradable polymeric carriers based on poly-α-amino acids. These polyplexes should transfect target cells which are supposed to be seeded on polyimide membranes. The biodegradable polymer membrane will be implanted into the retina or used as a coating for cardiovascular prosthesis. As a cover of the implantable membranes we used polymerized methacrylamide-modified gelatin forming hydrogels and mediating a growth support for transfected cells. We focus on material bio- and immunocompatibility/immunoacceptability. The results indicated a very good bio- and immunocompatibility of the gelatin B hydrogel both in vitro and in vivo. The gelatin B hydrogel did not cause erythrocytes lysis, stimulation of proliferation (spontaneous or mitogen-induced) of mouse or human lymphoid cells, neither production of cytokines or NO in vitro. Histological examination following subcutaneous...
