The 49th Symposium for the Society for Developmental BiologyCell-Cell Interactions in Early Development: June 28-30, 1990; Georgetown University, Washington, DC

Gerhart博士请求资助被邀请参加第49届发育生物学学会年度研讨会的演讲者的旅费，该研讨会将于1990年6月28-30日在华盛顿特区的乔治敦大学举行。研讨会的主题是“早期发育中的细胞-细胞相互作用”。演讲者将描述各种胚胎(果蝇、线虫、海胆、脊椎动物)、黏菌(Dictyostelius)和植物中的重要发育相互作用，通过分子、遗传学和胚胎学方法进行分析。其他发言者将讨论在细胞培养模型系统中研究的受体功能(生长因子)和信号转导的细胞生物学和分子方面，这可能与胚胎学研究有关。会议通常是中等规模(300-400名注册者)，一次举行一次单一平台会议(25-30名发言者)，并有60-80张海报。参加会议的有研究生、博士后研究员和高级研究人员。大多数发言者同意编写其发言摘要，以便在年度专题讨论会卷中发表。在过去几年里，在早期发育的细胞-细胞相互作用领域取得了很大进展，因此，举办这样一次研讨会来讨论和传播关于该领域状况的信息是很有价值的。

Dr. Gerhart is requesting funds for the travel of speakers invited to the 49th annual symposium of the Society for Developmental Biology, which will be held June 28-30, 1990 at Georgetown University in Washington D.C. The subject of the symposium is "Cell-cell interactions in early development". Speakers will describe developmentally important interactions in a variety of embryos (Drosophila, C. elegans, sea urchins, vertebrates), in slime molds (Dictyostelium), and in plants, as analyzed by molecular, genetic, and embryological methods. Other speakers will discuss cell biological and molecular aspects of receptor function (for growth factors) and signal transduction as studied in cell culture model systems, which are likely to have relevance to embryological studies. The meeting is usually of medium size (300-400 registrants) with a single platform session held at a time (25-30 speakers), and with 60-80 posters. It is attended by graduate students, postdoctoral fellows, and senior researchers. Most speakers have agreed to prepare summaries of their presentations for publication in the annual symposium volume. %%% Progress in the area of cell-cell interactions in early development have been substantial in the last few years and it is therefore valuable to hold such a symposium to discuss and disseminate information on the status of the field.
