Tissue Engineers Creating Complex Tissue They Call Living Legos

 Living Legos: Polymer building blocks whose complexity mimics that of human tissues.

Tissue engineers are ambitious. If they had their way, a dialysis patient could receive a new kidney made in the lab from his own cells, instead of waiting for a donor organ that his immune system might reject. Likewise, a diabetic could, with grafts of lab-made pancreatic tissue, be given the ability to make insulin again. But tissue engineering has stalled in part because bioengineers haven’t been able to replicate the structural complexity of human tissues. Now researchers have taken an important first step toward building complex tissues from the bottom up by creating what they call living Legos. These building blocks, biofriendly gels of various shapes studded with cells, can self-assemble into complex structures resembling those found in tissues.

The Military Plans To Regrow Body Parts

 The Military Plans To Regrow Body Parts

The US Military believes that humans will someday be able to regrow their limbs much like reptiles

The Department of Defense has announced the creation of the Armed Forces Institute of Regenerative Medicine to ‘harness stem cell research and technology… to reconstruct new skin, muscles and tendons, and even ears, noses and fingers.’ The government is budgeting $250 million in public and private money for the project’s first five years, and the NIH and three universities will be on the team.
