The formation of a fully functional organism requires the morphogenesis of cell and tissue structures during development. It is important to understand the mechanisms that mediate morphogenesis, since cell and tissue structures are crucial to physiological function. Here, we studied basal epithelial tissue folding as a model to determine the mechanisms of morphogenesis. We investigated a highly conserved basal tissue fold known as the midbrain-hindbrain boundary ...

Elucidating the molecular mechanisms that play a role in cellular morphogenesis is critical to our understanding of brain development and function. The midbrain-hindbrain boundary (MHB) is one of the first folds in the vertebrate embryonic brain and is highly conserved across species. We used the zebrafish MHB as a model for determining the molecular mechanisms that regulate these cell shape changes. Cellular morphogenesis is tightly regulated by signaling pathways that rearrange the cytoskeleton and produce mechanical forces that enable changes in cell and tissue morphology. The generation of force within a cell often depends on motor proteins, particularly non-muscle myosins ...
