Seminar & Symposium/Admissions





講演者: 石谷 太 (群馬大学 生体調節研究所 個体統御システム分野  教授)

演題: New cell-cell communication systems supporting tissue morphogenesis and homeostasis.


日時: 2月28日(水) 12:00-13:00

会場: 発生医学研究所1階 カンファレンス室



In our body, cells recognize its position and roles via cell-cell communication and behave appropriately. Such cell behavior supports tissue morphogenesis and homeostasis, and its dysregulation is involved in a variety of diseases, including cancer and diabetes. We are investigating the molecular basis of cell-cell communication and behavior in animal body, using zebrafish in vivo imaging, molecular genetics, molecular and cell biology, and biochemistry.

In the first half of this seminar, I will show that “cell-cell communication-mediated abnormal cell elimination (cell competition)” is involved in proper formation of the Wnt/β-catenin signaling-mediated tissue patterning. In the second half, I will talk about the communication between healthy cells and cancerous cells in cancer development and the importance of inflammatory signaling in primary tumorigenesis. Finally, I’d like to discuss about the powerfulness of “small fish in vivo cell biology” in medical and pharmaceutical studies.
