Is the medicine based on the culture of stem cells to regenerate damaged organs or tissues, as a result of diseases or accidents. These applications are posed as a future possibility in diseases such as Parkinson’s, Alzheimer’s or conditions such as diabetes. As these cells are treated there is the future possibility that we could eliminate problems related to donated organs and patients rejecting transplants.
This engineering is a specialty that applies the principles of engineering and life sciences to the manufacture of biological substitutes that maintain, improve or restore the function of organs and tissues in the human body.
Tissue engineering essentially uses cells cultured and / or genetically modified in the laboratory as engineering material.
It also uses 3D structures that can mimic the structure of an organ. These serve to replace part of a damaged organ that has stopped developing its function or as a vehicle to transport cells and molecules in its interior to the target tissue or organ.
Currently, tissue engineering plays a relatively small role in
the treatment of patients. Additional bladders, small arteries, skin grafts, cartilage and even a complete trachea have been implanted in patients, but the procedures are still experimental and very costly. While more complex organ tissues such as heart, lung and liver have been successfully recreated in the laboratory, there is still much to be fully reproducible and ready to be implanted in a patient. However, these tissues can be very useful in research, especially in the development of drugs. By using functional human tissue to help select medicines, candidates could accelerate development and provide key tools to facilitate personalized medicine, while saving money and reducing the number of animals used for research.
