Senescence scoring of public data sets. Datasets tested were: irradiated and non-irradiated colorectal tumour and normal tissue (GSE15781); doxorubicin and 5-FU treated breast cancer cell lines (GSE1647); mesenchymal stem cells cultured to replicative senescence (GSE9593); a melanoma progression set (GSE4587). All sets were scored using (A) All markers from Table 1, (B) DAS markers, (C) mSS markers. Median senescence scores are shown with bars representative of the maximum and minimum values. In the case of the hMSC set, the time-course data are derived from the cells of a single donor without replication and therefore, no bars are shown.
