Dr Anestis Tsakiridis
Brief career history
We aim to define the molecular basis of cell fate decisions during human embryonic development through the use of human pluripotent stem cells (hPSCs). We focus particularly on the in vitro modelling of the events guiding the “birth” of the spinal cord and trunk musculature from a common precursor population known as Neuromesodermal Progenitors (NMPs) during embryonic axis elongation.
We are also interested in another multipotent embryonic progenitor population known as the neural crest (NC). Depending on their position along the anteroposterior (A-P) axis, NC cells give rise to various specialised cell types, such as peripheral neurons, neuroendocrine cells and skeletal cells in the head. We have defined the culture conditions directing the generation of NMPs from hPSCs as well as their differentiation into either neural or mesodermal cells (Gouti, Tsakiridis et al., 2014 PloS Biology; Frith et al. 2018 eLife). We have also established efficient protocols for the in vitro production of human NC cells corresponding to most A-P levels and found a close link between NMPs and the precursors of trunk NC cells (Frith et al. 2018 eLife).
Using these in vitro systems we are trying to address the following questions:
1) How do embryonic cells proceed from pluripotency to NM bipotency?
Our ultimate goal is to exploit the knowledge from addressing the above questions in order to achieve the precise and efficient engineering of NMP- and NC-derived cell types for regenerative medicine and disease-modelling applications.
