Tissue engineering applies knowledge of biology, engineering and materials to be able to recreate tissues and organs that are similar to what we have in living organisms. For that, materials with the capacity to mimic the tissues of our body, specific tissue cells or stem cells and growth factors are needed to be able to talk and organize the cells in a similar way as it is found in the body.
These tissues and organs manufactured within the laboratory can simulate physiological conditions, that is, health as a skin or a liver. As we can also simulate a pathology (a disease) like the development of a tumor in the laboratory. Both types of models are very useful for us to better understand the biology of tissues as well as to test new products without using animals. In addition, one of the goals of tissue engineering is to be able to take these tissues produced in the laboratory so that they are available as transplants in cases of need for living beings.
Major advances have been made in recent decades, such as, for example, the use of artificial skin to reduce and replace the use of animals in cosmetic tests. Still, several researches at companies and universities continue so that we can evolve these models, for example, by adding a way of nutrition similar to our blood vessels. It is still uncertain when we will have these tissues available for patient treatments, but this will definitely happen in the future!
