“Lineage trees and dynamics of blood cancers”
ABSTRACT: I will talk about some efforts in my lab to understand how the differentiation and proliferation dynamics of mutated blood stem cells deviate from that of healthy stem cells in certain types of blood cancers. We have been able to infer the history of expansion of cancer in individual patients by reconstructing the lineage tree of the cancer cells from the pattern of naturally occurring somatic mutations in each cell’s genome. I will also talk about how we can use synthetic biology to record each cell’s lineage history in its own DNA, circumventing the need for naturally occurring somatic mutations.
