Cells Tissues Organs', formerly 'Acta Anatomica', is a well-established journal offering rapid exchange of information gained from experimental and theoretical investigations on all aspects of the formation and transformation of biological structure. Starting in 1945 as a journal devoted to gross anatomy, histology and neuroanatomy, it has continually broadened its scope to also cover work from cell biology, developmental biology and neuroscience. Beginning in 1999, the journal will have a new emphasis on the emerging fields of tissue engineering, artificial organs, in vitro systems, transplantation biology and computational neuroscience ñ areas which are beginning to use the rapid progress of cell and developmental biology, and neuroscience. With a new name and this new focus, 'Cells Tissues Organs' offers an attractive forum for information exchange in these areas of researc. High-quality papers from more traditional fields of biology will also be accepted. The same rapid and fair peer review and the exquisite production quality that distinguished 'Acta Anatomica' will continue to be the standard for 'Cells Tissues Organs'.
