This project aims to identify the key molecules controlling the formation of the nose and adenohypophysis. These organs develop from adjacent discrete ectodermal thickenings called cranial placodes. These placodes are therefore essential for the development of both sensory and neuro-endocrine systems. We have identified a specific cell population located in the very early central nervous system that is crucial for development of the telencephalon (forming the cortex in human). This special signalling cell population also lies adjacent to the precursors of both nose and adeno-hypophysis. We will explore the role of the signalling cell population (and its known secreted molecules) in controlling the development of these placodes. The cellular and molecular mechanisms leading to the establishment of both the nose and the hypophysis are not yet understood and this study will bring some novel understanding of these processes. It will also participate to the understanding of human genetic abnormalities affecting the development of olfaction, and hormonal dysfunction due to failure in hypophyseal development.

该项目旨在确定控制鼻和腺垂体形成的关键分子。这些器官是从相邻的离散外胚层增厚称为颅基板。因此，这些基板对于感觉系统和神经内分泌系统的发育至关重要。我们已经确定了一个特定的细胞群位于非常早期的中枢神经系统，这是至关重要的端脑（形成大脑皮层在人类）的发展。这种特殊的信号细胞群也位于鼻和腺垂体的前体附近。我们将探讨信号细胞群（及其已知的分泌分子）在控制这些基板的发展中的作用。导致鼻和垂体建立的细胞和分子机制尚不清楚，这项研究将为这些过程带来一些新的理解。它还将参与对影响嗅觉发展的人类遗传异常的理解，以及由于垂体发育失败而导致的激素功能障碍。
