[Tissue engineering: a tool to understand the physiological mechanisms]

Tissue engineering is a new domain, which allows some very unique studies of many human physiological mechanisms. This technology, based on cell capacity to reproduce a three-dimensional tissue with or without the help of biomaterials, is an interesting approach to study cells in an environment quite similar to the in vivo context. This article summarizes the LOEX's (laboratory of experimental organogenesis) scientific endeavor in tissue engineering in order to better understand some physiological or pathological mechanisms. Thus wound healing, stem cells, graft vascularization and cell interactions are domains where tissue engineering has already made a significant impact.
