Schematic representation of the cell division outcomes and the intrinsic growth rates. Each of these is given by the product of the basal growth rate r and the probability of the respective outcome. a Parent cells replicate themselves originating daughter cells in their same class. b CSC differentiation occurs in two ways: if asymmetric, the S population remains unchanged; if symmetric, S decreases
