Modes of cell death as analyzed in pedigree of irradiated cells

Pedigree of a colony formed from a cell irradiated with 2.5 Gy. Each horizontal line represents the life of a cell, relative to the time of irradiation. Black: cells which continue to divide (clonogenic survivors) Red / orange : cells that die (apoptose) - but often after several divisions!
