Increased Integrin Expands Regenerative Capacity in α7BX2-mdx/utr^−/− Mice

Age (weeks)	C-met-positive cells	BrdUrd-positive central nuclei
3	1.2-fold	1.2-fold
5	2.0-fold*	1.72-fold*
10	1.75-fold*	1.68-fold*

The numbers of c-met-positive cells and BrdUrd-labeled central nuclei in hindlimb fibers of mdx/utr^−/− and α7BX2-mdx/utr^−/− mice were determined at 3, 5, and 10 weeks of age. The relative increases in theα 7BX2-mdx/utr^−/− mice compared to the mdx/utr^−/− animals are indicated. At least six animals per genotype were scored. 

^*Statistical significance by analysis of variance; P < 0.05.
