In depth bio-printers

摘要

Organovo's system is unlikely to be a lone entrant into the bio-printer market. Anthony Atala, of the Wake Forest Institute for Regenerative Medicine in North Carolina, is also working on a system that can print new skin directly onto burns, making it suitable for use in war zones.rnAtala has already grown organs by seeding cells onto a cast polymer scaffold; his team has produced bladders, skin and erectile tissue. But bioprinting allows the scaffold to be eliminated and speeds up the process from six weeks to almost instantly.
