Tissue Growth and Developmental Pattern Formation
Individuals of the same species differ in size, but their organs have reproducible proportions and patterns of cell types. This requires the coordination of tissue growth with the generation of diverse cell types during development. We study how this coordination is achieved in the vertebrate neural tube, the embryonic precursor of the spinal cord and brain. In this organ, an elaborate pattern of multiple types of neuronal precursors forms along the dorsoventral axis at the same time as the tissue increases considerably in size. This fascinating process is orchestrated by signaling molecules, called morphogens, which are secreted from the opposite poles of the neural tube and form gradients of concentration in the tissue. While it is well established that morphogens instruct cells about their identity, many questions are still open. How do cells integrate signaling from opposing morphogen gradients? How do morphogens control tissue growth? How does tissue growth influence morphogen signaling and pattern?
To address these questions, we develop and use quantitative experimental approaches. We work in close collaborations with physicists to relate experiments to theoretical frameworks. We are particularly interested in imaging the dynamics of morphogen signaling and growth in living tissues. Our work incorporates a range of models, from mouse and chick embryos to mouse embryonic stem cells.
We are looking for outstanding postdocs and students interested in working on vertebrate neural tube development in an interdisciplinary environment. Candidates with background in developmental, cell or molecular biology or at the interface between biophysics and biology are encouraged to apply.
