Bioprinting is coming of age: Report from the International Conference on Bioprinting and Biofabrication in Bordeaux (3B'09).

The International Conference on Bioprinting and Biofabrication in Bordeaux (3B'09) demonstrated that the field of bioprinting and biofabrication continues to evolve. The increasing number and broadening geography of participants, the emergence of new exciting bioprinting technologies, and the attraction of young investigators indicates the strong growth potential of this emerging field. Bioprinting can be defined as the use of computer-aided transfer processes for patterning and assembling living and non-living materials with a prescribed 2D or 3D organization in order to produce bio-engineered structures serving in regenerative medicine, pharmacokinetic and basic cell biology studies. The use of bioprinting technology for biofabrication of in vitro assay has been shown to be a realistic short-term application. At the same time, the principal feasibility of bioprinting vascularized human organs as well as in vivo bioprinting has been demonstrated. The bioprinting of complex 3D human tissues and constructs in vitro and especially in vivo are exciting, but long-term, applications. It was decided that the 5th International Conference on Bioprinting and Biofabrication would be held in Philadelphia, USA in October 2010. The specially appointed 'Eploratory Committee' will consider the possibility of turning the growing bioprinting community into a more organized entity by creating a new bioprinting and biofabrication society. The new journal Biofabrication was also presented at 3B'09. This is an important milestone per se which provides additional objective evidence that the bioprinting and biofabrication field is consolidating and maturing. Thus, it is safe to state that bioprinting technology is coming of age.
