title: Charting Developmental Dissolution of Pluripotency.
abstract: The formation of tissues and organs during metazoan development begs fundamental questions of cellular plasticity: How can the very same genome program have diverse cell types? How do cell identity programs unfold during development in space and time? How can defects in these mechanisms cause disease and also provide opportunities for therapeutic intervention? And ultimately, can developmental programs be exploited for bioengineering tissues and organs? Understanding principle designs of cellular identity and developmental progression is crucial for providing answers. Here, I will discuss how the capture of embryonic pluripotency in murine embryonic stem cells (ESCs) in vitro has allowed fundamental insights into the molecular underpinnings of a developmental cell state and how its ordered disassembly during differentiation prepares for lineage specification.
