Research Summary

Hidehiko Inomata(Ph.D.)

Developmental processes take place through the exchange of information by cells within the constrained spatial environment of the embryo. Such intercellular communication is mainly regulated by a morphogen gradient. In order to ensure that development based on a simple morphogen gradient is stably reproducible, cell-cell communications mediated by morphogens need to be robust against perturbations. In our lab, we address the analysis of morphogen dynamics and extracellular fluid dynamics to study how developmental robustness is maintained. We are also working to develop methods for controlling the shape of morphogen gradients to spatiotemporally regulate the morphogen-dependent pattern formations.
