With the theme From egg to adult constructing the complexity of life the recent meeting of the International Society of Developmental Biologists ISDB in Sydney showcased recent progress in answering a broad range of questions on how the body of a multicellular organism is put together and how differences in body patterns evolve. This was the first ISDB congress since the publication of the initial sequence of the mouse genome in 2002 and there is no doubt that genome sequencing and the ability to study the expression of several thousand genes at once has facilitated progress in understanding how genes work to build an embryo. In his opening plenary lecture however Nobel laureate Sydney Brenner The Molecular Sciences Institute Berkeley USA warned that too much emphasis is placed on studying gene function. Brenner said we should thank the people who sequenced the genomes and tell them to go away and cautioned against high-throughput low-output research. He argued that rather than taking the bottom-up approach of studying individual gene function we should study the middle level the cell. In his view we need to know how many different cell types there are in the finished product and then we can start to understand how they got there. Cell lineages and differentiation Focusing on the earliest cell lineages Janet Rossant Samuel Lunenfeld Research Institute .
