POSTPONED TO SEPTEMBER 12th
On-site event
Presidentti auditorium, BioCity

Prof. Ellen Rothenberg, California Institute of Technology, USA
Epigenomic and gene regulatory network mechanisms controlling the dynamics of early T cell lineage commitment
Host: Riitta Lahesmaa (rilahes@utu.fi)

Coffee and sandwich at 11:45, first come first served!

Six PhD researchers and early-career postdocs are welcome to have a lunch in restaurant Mauno and discuss with Prof. Rothenberg after the seminar. This is a great possibility to learn hosting skills in friendly environment and create connections for future. Everyone is welcome to join, BioCity Turku will offer the lunch.

If you got interested, please send an email to biocityturku@bioscience.fi

The Rothenberg group studies the molecular mechanisms that are responsible for developmental lineage choice as hematopoietic stem cells differentiate into T lymphocytes. This is a complex process in which stem-cell multipotentiality is lost in steps that actually overlap with the initiation of T-cell specific differentiation events. Thus, it offers unique insights into the nature of “stem-ness” and the distinction between activation of a development program and irreversible commitment to that program. The approaches used in the lab are a combination of in vitro developmental biology, high-resolution characterization of individual cell developmental states, and molecular genetics of gene regulation. The Rothenberg group focuses on identifying the transcription factors and signaling events that induce T-lineage gene expression in an uncommitted precursor and determine also how they work to force the cell to relinquish other developmental options. Kinetic dissection of this complex process using in vitro differentiation systems and retroviral perturbation make it possible to solve the roles of individual regulatory molecules in successive, highly-defined developmental contexts.
