Meeting: The Developmental Biology of the Sea Urchin XXIV, The Marine Biological Laboratory, Woods Hole, MA, April 5-9, 2017

第24届海胆发育生物学（DBSU）会议将于2017年4月5日至9日在马萨诸塞州伍兹霍尔的海洋生物实验室（MBL）举行。自1980年以来，该会议大约每18个月举行一次，将国际社会的发育和细胞生物学家聚集在一起，他们将海胆作为研究的模型系统。最近有意将研究其他非规范模型系统的研究人员纳入其中，使其成为一个独特而重要的会议，为更广泛的发育生物学家社区服务。DBSU会议现在包括研究其他海洋无脊椎动物模型（如其他棘皮动物、被囊动物、半足动物、头脊索动物、软体动物、针孔动物、栉水母和海绵动物）的细胞和发育生物学的研究人员的参与。没有其他会议关注海洋无脊椎动物的比较发展，第24届“海胆会议”将继续作为促进非规范海洋无脊椎动物模型系统科学家之间合作的重要场所。会议分为全体会议、并行会议和海报会议，将重点介绍有助于我们理解受精卵如何成为具有许多不同细胞类型的胚胎的实验发现。此外，会议还将讨论诸如干细胞如何产生，动物如何再生失去的身体部位，以及海洋环境的变化如何对海洋无脊椎动物产生负面影响等问题。这些问题是公众非常感兴趣的，与人类健康有关。这次会议将促进年轻科学家的参与，以及来自通常在科学中代表性不足的群体的科学家的参与。此外，本次会议还将举办一个教育会议，以促进在发育生物学的本科教学和社区外展中使用海洋无脊椎动物胚胎。海洋无脊椎动物模型系统对我们目前对生物学的许多方面的知识做出了重大贡献，包括发育生物学。本次会议将重点介绍海洋无脊椎动物模型系统的多样性，这将为继续在系统发育上提供信息的双边和非双边分类群的发展和进化的系统水平比较提供机会。本次会议还将重点介绍我们对卵母细胞和胚胎中胚胎极性的分子机制的理解的最新进展，有丝分裂模式的调节机制，神经系统进化的新思想，形态发生的基因调控网络水平分析，干细胞的进化和再生的见解，以及生态和环境对胚胎和幼虫发育的影响。此外，还将有一场关于应用最新开发的相关技术（例如基因组编辑）来操纵非典型海洋无脊椎动物的发育的会议。

The 24th Developmental Biology of the Sea Urchin (DBSU) Meeting will be held at the Marine Biological Laboratory (MBL) from April 5-9, 2017 in Woods Hole, MA. Since 1980 this conference has been held approximately every 18 months to bring together the international community of developmental and cell biologists who use sea urchins as a model system for research. The recent deliberate inclusion of investigators working on other non-canonical model systems has made it a unique and important meeting for a broader community of developmental biologists. The DBSU meeting now includes participation of researchers working on the cell and developmental biology of other marine invertebrate models (e.g. other echinoderms, tunicates, hemichordates, cephalochordates, mollusks, cnidarians, ctenophores and sponges). There is no other meeting that focuses on the comparative development of marine invertebrates and the 24th 'Sea Urchin Meeting' will continue to serve as an important venue for promoting collaborations between scientists working on non-canonical marine invertebrate model systems. The meeting sessions, which are divided into plenary sessions, concurrent sessions and poster sessions, will highlight experimental findings that contribute to our understanding of how a fertilized egg becomes an embryo with many distinct cell types. Moreover, there will be sessions that address questions such as how stem cells arise, how animals regenerate lost body parts, and how changes in the marine environment are negatively impacting marine invertebrates. These questions are of great interest to the public and relevant to human health. The meeting will promote the participation of junior scientists and the participation of scientists from groups typically underrepresented in the sciences. In addition, this meeting will have an education session that will promote the use of marine invertebrate embryos in undergraduate teaching of developmental biology and in community outreach. Marine invertebrate model systems have made major contributions to our current knowledge of many aspects of biology, including developmental biology. The diversity of marine invertebrate model systems that will be featured at this meeting will provide opportunities to continue the systems level comparisons of development and evolution in phylogenetically informative bilaterian and non-bilaterian taxa. This meeting will also highlight recent advances in our understanding of the molecular mechanisms that specify embryonic polarity in oocytes and embryos, mechanisms regulating mitotic patterns, novel ideas on the evolution of nervous systems, gene regulatory network level analyses on morphogenesis, insights into the evolution of stem cells and regeneration, and the ecological and environmental influences on embryonic and larval development. In addition, there will be a session on application of relevant recently developed techniques (e.g. genome editing) to manipulate development in non-canonical marine invertebrates.
