B-C Western blots of G9a (B) and quantitative analysis (C) of the TAs of young and aged mice. D-E Representative images of G9a immunostaining (D) and quantitative analysis (E) of the TAs of young and aged mice; green, positive G9a staining; red, positive laminin staining; blue, DAPI-stained nuclei.
