Related Outline

The long-term goal in our lab is to understand how multicellular biological systems, which consist of a multi-hierarchical structure “genome-cell-tissue,” self-organize and establish order during embryonic development. Our bodies are composed of multiple organs with appropriate “shape” and “function”. During animal development, epithelial tissues, which consist of a single layer of cell sheets, repeatedly grow and deform to form an appropriate “shape”. The “function” of an organ depends on the property of cells, and cells appropriately differentiate and acquire functions to fulfill the physiological roles of their constituent organs. Thus, biochemical phenomena (gene expression and cell differentiation) and physical phenomena (morphogenesis) proceed simultaneously in the process of self-organization of multicellular organisms. For each organ to function correctly, both “physiological function” and “shape” must be in precise harmony. Using Drosophila embryogenesis as a model, my lab has previously revealed that, in addition to morphogenetic control under cell differentiation, the deformation of the epithelial tissue sheet affect the differentiation of cells, suggesting the existence of an autonomous ordering system based on mutual crosstalk between the biochemical phenomenon of cell differentiation and the physical phenomenon of tissue deformation. In addition, we have been establishing a single-cell transcriptome atlas of Drosophila embryos to observe genome hierarchy at the single-cell resolution in detail. By making full use of Drosophila genetics and imaging techniques in addition to single-cell genomics, we are working to elucidate the mechanisms of multi-hierarchical crosstalk on a genome-wide and whole-embryo scale.


In graduate school, Takefumi work on the identification and functional analysis of the micropeptides Pri of Drosophila in the group of Dr. Yuji Kageyama and received his Ph.D. from Nara Institute of Science and Technology in 2008. Then he moved to RIKEN Center for Developmental Biology as a postdoc in Dr. Shigeo Hayashi’s lab. He was appointed as Assistant Professor (PI) at Kyoto University/K-CONNEX in December 2015 and promoted as Junior Associate Professor in 2022.
