Wang, J. et al. Symmetrical and asymmetrical division analysis provides evidence for a hierarchy of prostate epithelial cell lineages.

But these daughters grow more slowly than the favoured daughters of unequal divisions, because their resources have to be divided between maintenance and reproduction.When Dr Watve ran the model, he discovered that the main determinant of whether symmetrical or asymmetrical division was favoured was the amount of food around.
