Each year, about 120,000 Americans need organ transplants, yet the demand for donor organs far outweighs the supply. The solution: Bioprinting. A 3-D printer is used to dispense different cells, creating layers of cells that form tissue. So far, artificial organs are successfully functioning in animals. Mice, for instance, were able to conceive and give birth by means of prosthetic ovaries.
However, as this new industry emerges, so does the opportunity to capitalize on it. A company in China estimates that the market in America for artificial livers is approximately $3 billion annually. With that sort of potential for profits, larger companies have taken an interest in the future of bioprinting. Well-known companies are making significant progress printing skin for burns and ulcers. A company in Pennsylvania has developed a method to print skin directly onto the patient by spraying stem cells onto the area in need of new skin. Such interest by major companies is advancing this new technology.
From The Economist, “Printed human body parts could soon be available for transplant”
Excerpt from article:
But a lack of suitable donors, particularly as cars get safer and first-aid becomes more effective, means the supply of such organs is limited. Many people therefore die waiting for a transplant. That has led researchers to study the question of how to build organs from scratch.
