Typical YAP/TAZ expression profile in tissues/organs during normal development and homeostasis. (A) Early embryonic and fetal development are typically associated with high levels of YAP/TAZ activity, which are gradually downregulated after birth, as growth during the juvenile phase slows down, (B) finally reaching basal levels at the quiescent state of mature adult tissues/organs. (C) At the onset of tissue/organ injury, the mobilization and rapid proliferation of endogenous adult stem/progenitor cells are associated with highly elevated YAP/TAZ expression levels, which (D) return to basal levels of the quiescent state after organ/tissue healing and regeneration is completed.
