Journal of Tissue Engineering is an open access journal. The aim is to provide a rigorously peer-reviewed and open access forum for the publication of scientific research in the field of tissue engineering and its clinical application. The journal has broad ranging interests from the fundamentals of stem cells and progenitor cells and their expansion to viable numbers coupled with an understanding of their differentiation, the utilisation of bioreactors for three dimensional culture and studies of phenotypic changes, particularly in stem and progenitor cells, both short and long term, ex vivo and in vivo implantation both in preclinical models and also in clinical trials.
