SOM profiling of DNA methylation over the time-course of differentiation in aged versus young adult HDMCs. (a) Demonstrates a larger number of hypomethylated and hypermethylated CpG sites in aged HDMCs, particularly at 7 days of differentiation, compared with young adult HDMCs. (b) Venn Diagram analysis depicting the 24 common CpG sites that were altered at every time point of differentiation between aged and young adult muscle HDMCs cells (0, 72 h, 7d and 10 d). c. As with the above analysis in 3a, SOM profiling identified that 16 out of these 24 CpG’s also demonstrated the most alterations in methylation at 7 days of differentiation in aged cells.
