Tissue Engineering Essay -- Organ Transplant Medical Health Essays

Tissue EngineeringTissue engineering, labelled by Time.com as the number one hottest job for the 21st century, holds capacious potential for medicine and the discourse of chronic diseases and disorders. With tissue engineering, familiar problems corresponding the rejection of foreign tissue by the soundbox, the severe shortage of organ donors, and the inefficiency of false devices may be solved. However, this cutting edge biotechnology has already spurred exquisite controversy over the ethics and morality of creating spare human body parts. The goal of tissue engineering is to flex tissues and neo-organs that wad be use for transplants. Tissue engineers must first decide what type of cell they expect to use and stimulate to grow. Because animal cells may be unsafe and jilted by a human immune system, human cells are preferable when the end goal is an organ for human use. Embryonic stem cells may be used, but it is difficult to be able to coax the cells to compare into t he specific cells needed for the organ (e.g. liver cells). Progenitor cells are not fully differentiated and thus can be stimulated to grow into different cell types. For example, there is a progenitor cell that can form into either bile-producing cells or cells that line bile ducts, depending on the commission it is manipulated in culture. For a wound or bone fracture, an injection of suppuration factors can stimulate the specific cells around the wound to regenerate and urge healing. The specific cells can also be grown in bioreactors that simulate the conditions of a human body and expose the cells to growth factors. Using the polite cells, tissue engineers then seed them on a molded hold. The scaffold is made out of a biodegradable material that disintegrat... ...th kidney disease, and she, the recipient of two brand-new engineered kidneys, displays a quasi-jealousy over the patient who will have dialysis treatment and receive attention every week. With neo-organs readil y available to replace ghoulish and worn out organs, what will happen to doctor-patient relations? We may be able to one day perfect tissue engineering, but a flawless science will not do much so long as we have emotionally flawed humans the like Olivia and Troy.
