    The Wnt family of developmental regulators were named after the Drosophila segmentation gene wingless and the murine proto‐oncogene int‐1. Homology between these two genes connected oncogenesis to cell‐cell signals in development. I review how wingless was initially characterized, and cloned, as part of the quest to identify developmental cell‐to‐cell signals, based on predictions of the Positional Information Model, and on the properties of homeotic and segmentation gene mutants. The requiremen…Read more

    Size isn't everything
    with David Tyler
    Bioessays 25 (1): 5-8. 2003.
    Much progress has been made recently towards uncovering the mechanisms that control the size to which organisms and their organs grow, and identifying some of the genes responsible. Size control, however, is only half of the equation. In growing to the right size, tissues must also grow to the right shape. A recent paper1 suggests that a hitherto overlooked cellular behaviour governs the size and shape of a growing tissue, and issues a challenge to developmental biologists to identify the molecu…Read more
