Philippos
MOURIKIS
Academic Researcher (CR)
Research Interests:
Regulation of satellite cell quiescence with a focus on Notch signallng. Using innovative cell isolation techniques, our aim is to identify and characterize the factors that drive satellite cells into quiescence (development/regeneration), maintain them at this cell state during homeostasis, but also the factors that ignite their activation (regeneration and pathological conditions).
Strategy for muscle maintenance:
Regulation of how a ball can go form one side of the court to the other with a focus on the yellow ball.
What the Relaix lab says about Philippos:
"Outstanding researcher with a true academic vision"
"Greece contributed a lot in arts, philosophy, democracy, science... and it still is by giving us such a brilliant biologist. "
