[Tissue engineering of vascularized myocardial prosthetic tissue. Biological and solid matrices].

Tissue engineering of bioartificial myocardial tissue will become an increasingly important therapeutic approach in the near future but supply of oxygen and nutrients as well as evacuation of metabolic products represent a critical obstacle in tissues with a thickness of 100 µm and above. Viability of seeded cells in the myocardial patch is positively correlated with its function and thus early sufficient vascularization is mandatory. The choice of substrate, structure of matrices, specific cellular seeding and addition of growth factors contribute to this necessary vascularization process.This review article gives an overview of the current state of research on recent myocardial tissue engineering utilizing natural and solid substrates (urinary bladder, gall bladder, small intestine, stomach, peritoneum, omentum, uterus, skeletal muscle, diaphragm and cardiac muscle) with a special focus on the results of vascularization of bioartificial tissue for each approach.
