Developmental Biology in Finland

Cover legend

Three successive generations of scientists at the University of Helsinki have been instrumental in building a solid tradition of experimental research in developmental biology in Finland. The work of Gunnar Ekman (1883-1937, top) was essential to the promotion and diffusion of the experimentalist tradition and shaped the subsequent career of Sulo Toivonen (b. 1909, bottom left). During the difficult post-WWII years, Professor Toivonen trained a team of young researchers, established a network of international contacts for Finnish scientists and forged a Finnish tradition in developmental biology. Lauri Saxén (b. 1927, bottom right) joined Professor Toivonen in the early 1950´s and together they produced numerous studies which have since become classics in the field. Today, Professor Saxén and his own team, as well as the other authors included in this special issue, represent the final phase of consolidation of developmental biology in Finland. For details, see "The Finnish tradition of developmental biology" by Anto Leikola in this issue.
