Regulation of mesenchymal stem to transit amplifying cell transition in the continuously growing mouse incisor [Microarray Expression]

ABSTRACT: Regulation of transit amplifying cell formation from self-renewing stem cell is fundamental process for cell replacement in a controlled way. Here we analyse the properties of a population of mesenchymal TACs in the continuously growing mouse incisor to identify key components of the molecular regulation that drives proliferation. Using gene microarray profiling, we show that the polycomb repressive complex 1 acts as a global regulator of the TAC phenotype by its direct action on the expression of key cell cycle regulatory genes and also by regulating Wnt/b-catenin signalling activity. Analysing the properties of mesenchymal transit amplifying cells population and identifing key components of the molecular regulation that drives proliferation.
