BBS Graduate program, HMS

Co- director with Iain Drummond

Overview: The purpose of this class is to teach critical thinking about development and regenerative biology. Student involvement in discussions and critique of published work is the core strength of this course. We prepare students to critically assess the current state of the art in stem cell biology and apply the same approaches to their own research.

Course Description: This course explores developmental mechanisms that persist throughout the life cycle, examining pluripotency and cell fate restriction in embryos and adult tissues. The course is divided into 3 Units.

Unit 1 (4 Fridays) will examine general developmental mechanisms that are essential for both tissue formation and self-renewal. Special emphasis will be given to lineage restriction and cell fate determination in embryos.

Unit 2 (4 Fridays) will analyze the renewal and repair of specific adult tissues. We will emphasize in vivo approaches to understanding how tissues renew or repair themselves following normal wear or wounding.

Unit 3 (4 Fridays) will explore new frontiers of stem cell and regenerative biology. We will cover regeneration in emerging model organisms, cancer stem cells, and bioengineering approaches to regenerative medicine. In the final class, we will discuss general themes from the course content.
