In most cell subsets, the percentage of cells that incorporated BrdU was lower in Lama2
-/- muscles, but higher in mdx muscles, than in healthy control muscles. A. In all cell subsets except Sca-1-/CD45+, the percentage of cells that incorporated BrdU during 24 h in vivo was significantly increased in mdx cells compared to normal cells (see text for statistics). B. The percentage of cells that incorporated BrdU in Lama2
-/- muscles was significantly decreased compared to normal muscles in all subsets of Lama2
-/- cells with the exception of the rare double-positive Sca-1+/CD45+ subset in which incoporation was similar in diseased and healthy muscles (see text for statistics). Error bars represent standard deviation with n = 3. * indicates that the value for the mdx or Lama2
-/- muscles differed significantly from the corresponding control at P < 0.05.
