Comparison of chromosome arm specific differences in telomere length. Each dot represents the telomere length from one chromosome arm from one cell sample matched to the same chromosome arm from a second cell sample. 6A X-axis: hMSC before transduction. Y-axis: hMSC-telo1 after transduction. 6B X-axis: hMSC-telo1 before irradiation. Y-axis: hMSC-telo1 after irradiation with 2.5 Gy. Corresponding correlations can be found in table 2.
