The stromal tissues of the heart include the connective tissues, blood vessels, and nerves supporting the myocardium. Most important, tissue engineering might help some of the 120,000 people on the waitlist to receive donated kidneys, livers, or other organs. The game changer for 3D printing will be in human tissue printing: printed livers, hearts, ears, hands and eyes, or building the smallest functional units of tissues, which can lead to the fabrication of large tissues and organs. This type of cellular therapy is an all-natural way to help repair damaged tissue in the body. Everyone knows that a balanced diet consists of the right proportions of dairy, vegetables, fruits and protein, but not many are aware that some people heal faster than others, whether the problem is a complicated broken limb or something as painful as soft tissue damage. Tissue repair increases with the toxicant dose until a threshold dose is reached, beyond which it is delayed and impaired due to inhibition of cellular signaling, resulting in runaway secondary events that cause tissue destruction, organ failure, and death [90]. In fact, about one-third of all women are affected by prolapse or similar conditions over their lifetime. To make synthetic organs and tissues, scientists need to be able to control stem cells so that they can form into different types of cells, such as liver cells and blood vessel cells. These forms of stem cell therapy can be painful, and the cells age with you. Tissue is the major structural component of the organ while organs are the structural components of the organ system.
