The Journal of Cellular Physiology publishes reports of high biological significance in all areas of eukaryotic cell biology and physiology focusing on those articles which adopt a molecular mechanistic approach to investigate cell biology. In particular the journal actively encourages the submission of high-interest papers investigating the regulation of growth and differentiation by growth factors and cytokines signal transduction by growth factors cytokines and their cognate receptors and the conditions which influence the expression and function these molecules. Similarly the journal actively encourages the submission of manuscripts exploring the regulation of growth and differentiation by cell adhesion molecules as well as the interplay between these processes and those induced by growth factors and cytokines. Studies on the genes and processes that regulate cell cycle progression and phase transition in eukaryotic cells and the mechanisms which determine whether cells enter quiescence proliferation or undergo apoptosis are also welcomed. Finally the investigation of the basic changes which differentiate cancer cells from normal cells including studies on the properties and functions of oncogenes and tumor suppressor genes will remain as one of the major interests of the Journal.
