Biology of the Cell publishes original findings and reviews concerning the structure and function of cells, organelles and macromolecular assemblies. The journal is particularly interested in studies of cellular organisation and regulation at the molecular and supramolecular levels. Both functional and descriptive studies that bring new information and further the understanding of cell biological processes are welcome. Areas of interest include, but are not restricted to, cellular architecture, cell morphogenesis, cell mobility, membrane and organelle dynamics, cell division and cell differentiation. Submission of manuscripts treating such topics in the context of developmental biology is especially encouraged. In 1998, a special issue was devoted to "Cell Cycle" and was dedicated to Yoshio Masui.
