Abstract

Intra-tumor heterogeneity of cancer cells hampers the design of effective therapies and yet it is poorly reproduced in experimental models. A recent report by Eirew at al. provides an in-depth analysis of genetic heterogeneity of breast tumor xenografts and shows that changes in clonal diversity might not be stochastic.
