Engineering joints and arteries
Thursday, 17 January, 2002
Scientists are building complete blood vessels and the inner surfaces of joints in their laboratories.
The aim is to make these and other completely engineered structures available for transplant into patients suffering from conditions such as coronary thrombosis and osteoarthritis.
Eventually the researchers - at the universities of Manchester and Liverpool (UK) - plan to assemble complete replacements for parts of organs including kidney and liver, as well as muscle, heart and even brain tissue.
These products of tissue engineering, as the process of building them is called, will come equipped with the ability to communicate with their surroundings in the body they are implanted into, by sending the correct signals to attract blood vessels to grow into them to supply their needs.
