Adaptation, plasticity, and extinction in a changing environment: towards a predictive theory.

abstract：:The acquisition of terminal cell fate and onset of differentiation are instructed by cell type-specific master control genes. Loss of differentiation is frequently observed during cancer progression, but the underlying causes and mechanisms remain poorly understood. We tested the hypothesis that master regulators of d...
