Bio 488: Selected Topics in Development Professor Elena Casey Rm 438 Reiss Science Building Wednesday 2:50-4:55 Goals: To learn and discuss some of the major topics in human embryonic development. How multicellular animals develop has long been a central area of study in the biological sciences. Technological innovations in recent years have stimulated a virtual explosion of new information and conceptual breakthroughs, providing molecular mechanisms for fundamental developmental processes. The objective of this course is to introduce you to these concept and techniques by reading and discussing primary research literature in developmental biology. We will focus on the genetic regulation of developmental pathways and processes. However, organismal, cellular, and biochemical perspectives will also be discussed. Rather than exploring a wide spectrum of developmental systems and developmental processes, this course is designed to examine selected topics in pattern formation and cell fate specification in considerable depth. We will also discuss how some of this research is portrayed in the press and examine some of the more controversial aspects of development and discuss the ethics of this research. However, this course emphasizes research articles and reviews, providing a particularly detailed study of specific processes in vertebrate development. With this approach, the goal is to encourage use of resources that will allow students to learn not only important developmental facts, but also how to think about underlying mechanisms that make the processes dynamic and how to critically read current literature. Previous course work in cell and/or developmental biology would be useful. Format: Each class period we will first discuss a review paper. To do this, every person in the class will present the answer to a question provided the previous week. Part of your grade is dependent on the lucidity and precision of your answers each week. Next we will discuss ethical issues and/or representations of this subject in the media. Finally, a student will do a powerpoint presentation of the research paper. This presentation must be discussed on the Monday before class with Dr. Casey and the completed version must be sent to her via email the night before. Textbooks and reading: The review and research papers will be handed out in class the week prior to discussion. They will also be posted on blackboard Required book: Gilbert, Tyler, and Zacki.

You will be given a topic and one paper on which you will lead a discussion. Give an introduction of the subject…[e.g. Development of the olfactory system involves…This subject is of particular interest because………. The researchers address this problem by using this approach……. ] Then systematically go through each figure. You must show the figure by powerpoint or some other equivalent program. You may ask people for their opinions to describe a figure but be ready to answer detailed questions on the paper.
