Artificial bone gets natural gradually

  September 1/8, 2008
Coat a porous material with a gene-delivering virus in decreasing amounts from one end to the other and you can grow artificial bone that gradually transitions to ligament rather than ending abruptly.

The technique involves seeding a three-dimensional scaffold in decreasing concentrations with a retrovirus carrying a gene that triggers bone cell formation. Cells that fill the scaffold turn to bone where the concentration is high and ligament where it's low, resulting in a more natural transition between bone and soft tissue.

The resulting material could be used in replacement surgery to repair bone and ligament damage.
