Workshops

Day 1 (June 19 (Wed)) 14:30-16:30

Workshop 01：Stem cells and cell plasticity across plants and animals: their roles in development, homeostasis, and regeneration (in Japanese)

Chairpersons: Yuichiro Nakajima (Univ. of Tokyo) Aiko Sada (Kyushu Univ.)

A brief introduction： 動物の多くは初期発生で多能性幹細胞を失い、成体では組織幹細胞が恒常性維持や再生に寄与する。一方、植物は多能性幹細胞の維持やリプログラミングによって永続的な成長や高い再生能力を生涯にわたって示す。本ワークショップでは、動物と植物の発生や恒常性、再生における幹細胞制御や可塑性についての最新の成果を紹介して議論する。動植物間での幹細胞機能や細胞運命決定の類似性や相違点を理解しながら、多細胞体制を実現する自己組織化や個体維持といった共通テーマへの理解を深めることを目標とする。

Speakers: Yuichiro Nakajima (Univ. of Tokyo) Aiko Sada (Kyushu Univ.) Momoko Ikeuchi (NAIST) Yuki Kondo (Osaka Univ.) Yumi Konagaya (RIKEN BDR) Yuki Hirakawa (Gakushuin Univ.)

Workshop 02：New Development of Neurodevelopment (in Japanese／in English)

Chairperson: Yu Katsuyama (Shiga Univ. of Medical Science)

A brief introduction： 発生生物学的手法による脳の進化の解明は、これまでの２０年強において、大きく発展した研究分野であり、従来は異なった動物種の胚の組織染色による遺伝子やタンパク質の発現比較と、遺伝子機能阻害や過剰発現実験による分子発現制御の解明が中心であった。しかしゲノムワイドなシーケンス解析などの手法を導入することにより新しい比較形態学的解析が可能になった。そこで本ワークショップは異なったモデル動物を用いた神経発生学・比較神経形態学の研究の現状を示し、それによって我々の脳のなりたちを議論する場を提供する。

Speakers: Takeo Horie (Osaka Univ.) Hideaki Takeuchi (Tohoku Univ.) Yohei Shinmyo (Hamamatsu Univ. of Medical Science)

Workshop 03：Exploring the evolution of animal cell and tissue types through the lens of non-bilaterian development (in English)

Chairpersons: Nagayasu Nakanishi (Univ. of Arkansas) Gaku Kumano (Tohoku Univ.)

A brief introduction： Our understanding of animal development has advanced greatly through the studies of bilaterian models such as Drosophila and mice. However, bilaterians represent only one of the early-branching metazoans, which also include non-bilaterian groups - Cnidaria, Placozoa, Ctenophora, and Polifera. Therefore, fundamental mechanisms of animal development and their evolution cannot be fully understood by studying bilaterian development alone. Highlighting research on non-bilaterian lineage-specific traits and/or traits deeply shared between non-bilaterian and bilaterian animals, this workshop aims to explore knowledge difficult or impossible to obtain with bilaterian research only and to unravel fundamental mechanisms for generating diverse and complex cell types and tissues in animal development and evolution.

Workshop 04：Developmental Toxicology and toxicogenomics (in English)

Chairperson: William Ka Fai TSE (Kyushu Univ.)

A brief introduction： The drastic advancement in industrialization and technology, and the growth in human population in the past century have resulted in unprecedented environmental changes in the human history. The production of large amounts of synthetic  compounds as well as pollutants poses a risk to our ecosystem and induces negative effects on the health of wildlife and human beings. With the emergence of the global problem of chemical contamination, such as endocrine-discrupting chemicals (EDCs), Per- and polyfluoroalkyl substances (PFAS), and microplastecs, the adverse biological effects of such pollutants are gaining attention in the publics. There is an increasing need for the identification and quantification of all these ubiquitous chemical contaminants. Studies in toxicology field have been continuous be performed, however, more detailed reseraches on potential developmental hazardous of such chemicals are requried. It is especially important to understand the possible toxic effect on the developing embryo. The symposium will introduce the current developmental toxicology studies using various experimental models, and omics methods; and finish by discussing the future directions of the field. We hope tha tthe workshop could induce the concept of integrating the developmental biology in the toxicology studies.
