National University of Singapore has come up with a technique to grow tendons and ligaments that can be used to replace damaged ones. The breakthrough
came about by the development of a machine that is used in the process to stretch the developing tissue.
New Parts
The machine pulls on one end of the sheet, pulsing about once every second, and creating a tension similar to that which the tendon and ligament cells
experience inside the human body.
Apparently, this prompts the stem cells on the scaffold to start elongating, and turning into the tendon and ligament cells. 'If you didn't have
this pulling motion, you'd end up with ordinary, starfish-shaped cells,' said Prof Goh.
The team also rigged up a flow system, to make sure that the nutrients flowed over and through the scaffold in one way only. Seeming to sense the flow
of food, the cells then align themselves in a linear fashion - vital to the formation of the fibrous ligaments.

This is sure to help many people since there is no need to worry about rejection. Plus this hopefuly will be ready by the time I start needing
replacement parts.
