G0 phase zelle
WebG0 phase Most cells in adult tissues are in a transient (quiescent) or permanent (senescence) G0 phase. Cells in transient G0 can re-enter the cell cycle, a process under the control of cyclin D-CDK4/6. These complexes can sequester CDK inhibitors (p21 and p27) that bind to and prevent cyclin E -CDK2 activation ( Otto and Sicinski, 2024 ). WebJul 21, 2024 · The G0 state (non-cycling cells) in plants was proposed on the basis of observations by Clowes (1971), who found that the QC of maize roots contained a heterogeneous population of slowly cycling and non-cycling cells, as demonstrated by thymidine pulse-labelling experiments ( Clowes, 1971 ).
