This EMBO | EMBL Symposium will go beyond a description of the phenomena involving stem cell behaviour, programming and reprogramming. It will bring together researchers from different disciplines, who will address fundamental questions of totipotency as they relate to evolution, development and tissue specialization.
•Questions to be discussed include:
◦how a need for germline specification arose during the evolution of multicellularity from single cells to colonies with specialized cell types;
◦how the fertilized egg cell loses totipotency during formation of a multicelluar organism;
◦how chromatin-based mechanisms influence totipotency both at the cellular and transgenerational level; and
◦how the decision toward meiosis is achieved and regulated.
•Topics
◦From single cells to multicellularity
◦Keeping it all together: chromosomes and chromatin
◦Programming and reprogramming
◦Conservative vs progressive divisions (mitosis and meiosis)
◦Context matters
